Want this question answered?
When a sinusoidal alternating voltage is applied in a circuit, the resulting alternating current is also sinusoidal and has the same frequency as that of applied voltage .However, there is generally a phase difference between the applied voltage and the resulting current.This is how alternating-current circuit works.

V = I * R or I = ( V / R ) I = current (amps) V = Voltage R = Resistance The current in a circuit depends on the applied voltage and the resistance of the circuit.
By Kirchhoff's Voltage Law, the sum of the voltage drops around the series circuit will equal the voltage applied to the circuit.
The voltage is greater than the applied voltage, why?
both have to confront with resistance.
When an alternating voltage is applied to a purely resistive circuit, the resulting current is in phase with the voltage.
this is the amount of voltage a circuit can hold.
'A' and 'C' are saying exactly the same thing. The correct choice is 'D'. The complex impedance of a purely resistive circuit is purely real. Since there is no reactance, there is no phase shift, so the power factor is ' 1 ', KVA = KW, KVAR = 0, etc.

The phase angle between voltage and current in a purely resistive circuit is zero. Voltage and current are in phase with each other.
The voltage before it is hooked up to a resistive load.
An electric current through a resistive circuit can be increased by decreasing the resistive load or increasing the voltage of the circuit.
Any voltage that is fed into or "applied" to an electrical circuit is referred to as an "applied voltage".
V = I * R or I = ( V / R ) I = current (amps) V = Voltage R = Resistance The current in a circuit depends on the applied voltage and the resistance of the circuit.
For a series circuit, the applied voltage equals the sum of the voltage drops
The reason an AC voltage applied across a load resistance produces alternating current is because when you have AC voltage you have to have AC current. If DC voltage is applied, DC current is produced.
Voltage and current will be in phase for a purely resistive load. As a load becomes more inductive or capacitive, the phase angle between voltage and current will increase.
