Electrical appliances are not connected in series because current will be same through all the appliances connected whereas appliances have different current ratings and also that voltage decreases as more no. Of appliances are connected. Mark my answer as a Brainliest.
similarly, Which color wires go together?
US, AC:The US National Electrical Code only mandates white (or grey) for the neutral power conductor and bare copper, green, or green with yellow stripe for the protective ground. In principle any other colors except these may be used for the power conductors.
on the other hand, What happens if household electric appliances are connected in series?
If they are connected in series and one device gets fused , this may lead to the other devices losing connection and may also lead to the decrease in the functionality of the devices. Also this increases the load in the circuit. So, We should connect electrical appliances Parallel in a household circuit.
also, When two resistances are connected in series they have? The equivalent resistance of two resistors connected in series is the sum of the individual resistances. Figure 19: Two resistors connected in parallel. The reciprocal of the equivalent resistance of two resistances connected in parallel is the sum of the reciprocals of the individual resistances.
Do not use appliances if answer?
We should not use many electrical appliances simultaneously because this can lead to short circuit due to overload in the circuit. It can damage many of the appliances connected.
Do red and black wires go together?
If the red and black wires are connected together already and energized, yes you can do that but you will need a pull chain light or a remote control, if they are not switch controlled.
What is the difference between white and yellow electrical wire?
For example, white sheathing means that the inner wires are 14-gauge and yellow sheathing indicates that they are 12-gauge.
What color wires go together for a ceiling light?
Blue wire is for the light, if light is included with the fan. White wire is neutral. Green wire is for the ground. Red wire is sometimes included and acts as a conductor to carry power to the light kit.
Are different electric appliances connected in series or parallel in a house?
Electrical appliances are connected in a parallel arrangement in a house circuit because: Each appliance gets full voltage as resistance in a parallel arrangement is low. If one appliance fuses, it does not affect the working of other appliances.
Why household appliances are normally connected in parallel?
Answer: There is no division of voltage among the appliances when connected in parallel. The potential difference across each appliance is equal to the supplied voltage. The total effective resistance of the circuit can be reduced by connecting electrical appliances in parallel.
Which of the following appliances at home is connected using a series connection?
Answer: Freezers and Refrigerators. Explanation: Both use series circuits.
When two resistors are connected in series they have same value?
Series Resistor Equation
If two resistances or impedances in series are equal and of the same value, then the total or equivalent resistance, RT is equal to twice the value of one resistor. That is equal to 2R and for three equal resistors in series, 3R, etc.
Is current the same across resistors in series?
The same current flows through each resistor in series. Individual resistors in series do not get the total source voltage, but divide it. The total potential drop across a series configuration of resistors is equal to the sum of the potential drops across each resistor.
When two resistances are connected in parallel then the equivalent resistance is 6’5 ohm?
When two resistances are connected in parallel then the equivalent resistance is 56Ω. When one of the resistance is removed then the effective resistance is 2Ω.
Is it bad to have exposed wires?
A plug or electrical cord should not have exposed wiring. Exposed wires present a danger of electric shock or electrocution. Using an open front plug poses the risk of contact with live wires when plugging it to a electrical outlet. This also poses a risk of electric shock or electrocution.
What allows electricity to flow through it easily?
Materials that allow electricity to easily flow are called conductors. Think of a conductor on a train. … Materials that do not allow electricity to pass easily through them are called insulators. Rubber, glass, plastic, and cloth are poor conductors of electricity.
What is electrical safety rules?
15 Safety Precautions When Working With Electricity
- Avoid water at all times when working with electricity. …
- Never use equipment with frayed cords, damaged insulation or broken plugs.
- If you are working on any receptacle at your home then always turn off the mains. …
- Always use insulated tools while working.
Is red wire the same as white?
Black, red, white with black or red tape will always indicate a hot wire. … While white wiring is permitted— only when clearly marked with black or white tape—using any other color for a wire carrying current is strongly discouraged.
Which wire is positive when both are black?
If the multi-colored wire is black and red, the black wire is the negative wire, while the red one is positive. If both wires are black but one has a white stripe, the striped wire is negative, while the plain black wire is positive. Look in the owner manual to determine which wires are negative in a car.
What happens if you switch black and red wires?
If you switched the wires, what would happen? Red is positive charge, black is negative charge. If you aren’t running if you aren’t connected correctly.
Can I mix 12-gauge and 14-gauge wire?
More specifically, can you connect 14-gauge wire to 12-gauge wire? While this is possible, it is not recommended in order to prevent overloading. … For example, if the amp capacity of your breaker is 20 amps, you should only use 12-gauge wire, and if it’s 15 amps, the entire circuit should be 14-gauge.
Is 14-gauge wire always white?
Cable with white sheathing houses 14-gauge wire. … General lighting circuits are normally the primary use of 15-amp circuits wired with 14-gauge cable, although many homes are now wiring these circuits as 20-amp circuits.
Can you use a neutral wire as a hot wire?
A neutral wire returns electricity from the hot wire back to a grounded portion of the home’s electrical panel to complete the circuit. … Furthermore, neutral wires can be used as a hot wire if both ends are clearly marked with colored electrical tape (black or red) that corresponds to its repurposed function.
