How does voltage change across an appliance in a parallel circuit?
With the minor voltage loss in the wiring, the voltage drop across a single appliance is the total voltage in the circuit, and doesn't change when more devices are added in parallel.
Advantages of parallel circuit?
A parallel circuit can run several devices using the full voltage of the supply, varying the current to the need of each device. If one device fails, the others will continue running normally. If the device shorts, the other devices will receive no voltage, preventing overload damage.A series circuit divides the supply voltage among the devices with a consistent current. If one device fails, all other devices in the circuit will either fail to receive voltage or receive too much voltage and become damaged in the case of a short.An advantage of parallel circuits is increasing the power rating of the circuit and reducing the resistance.
What is the Difference between voltage controlled device and current controlled device?
The difference between a current control device and voltage controlled device is that for current controlled device, the current is constant and the voltage is variable while for a voltage controlled device, the voltage is constant and the current is variable.
What three devices are usually found in series with the Y terminal of a low voltage control circuit?

Can there be a different voltage across each component in a circuit?
Yes, if it is a series circuit. In an ideal parallel circuit, there is equal voltage in each leg. In a real circuit, results may vary if there is voltage loss in the wiring.
What is the best method to check for unwanted resistance in a circuit?
Do not add any unwanted device in the circuit. Have correct sized wire for the application and the load current.
How do you add a fixture to an electrical circuit?
Any devices that are added to a circuit and need the full line voltage to operate, are added in parallel to any other load devices or fixtures in the circuit.
How does voltage change across an appliance in a parallel circuit?
With the minor voltage loss in the wiring, the voltage drop across a single appliance is the total voltage in the circuit, and doesn't change when more devices are added in parallel.
What do you mean by Computers are susceptible to sudden surges or drops in electrical line voltage?
Computers are sensitive electronic devices violent voltage fluctuations can burn up individual components or corrupt your data.
Advantages of parallel circuit?
A parallel circuit can run several devices using the full voltage of the supply, varying the current to the need of each device. If one device fails, the others will continue running normally. If the device shorts, the other devices will receive no voltage, preventing overload damage.A series circuit divides the supply voltage among the devices with a consistent current.

What does the resistance of a circuit mean?
Resistance in a circuit is its ohmic value of the circuit. It is comprised of all of the devices and components that make up the circuit. This also includes the wire that carries the voltage to the load of the circuit.
What is the Difference between voltage controlled device and current controlled device?
The difference between a current control device and voltage controlled device is that for current controlled device, the current is constant and the voltage is variable while for a voltage controlled device, the voltage is constant and the current is variable.
How is a series circuit different from parallel circuit?
A parallel circuit is different in many ways from a series circuit: 1. In parallel, the voltage across all the devices connected is the same. 2. If a fault occurs in any device connected in parallel combo, then it has no effect on the operation of the other device. 3. In series circuit the current flowing through all the devices is the same while in case of the parallel one the voltage across all the devices is same.
Why would houses have parallel circuits?
So that the voltage across all devices is the same. In a series circuit voltage would vary across each load so would depend on what else was in the circuit.
What device uses the voltage in an electrical current?
A voltage, or potential difference, is what causes current to flow through a circuit. So all devices (called 'loads') require a voltage applied to them.

Fuses increase or decrease the voltage of a current electrcity?
Fuses have absolutely no effect whatsoever on the voltage applied to a circuit. Fuses are simply overcurrent protection devices, intended to disconnect the circuit in the event of a sustained overload current or a short-circuit fault current.
