'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.
When an alternating voltage is applied to a purely resistive circuit, the resulting current is in phase with the voltage.
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.
burn or burst
(15 volts) x (10 Amps) = 150 watts
when a resistive load is applied there is no phase angle difference between voltage and current. when a inductive load is applied there is phase difference between voltage and current. current lags voltage by an angle of 90 degrees for pure inductive load
When an alternating voltage is applied to a purely resistive circuit, the resulting current is in phase with the voltage.
When an alternating voltage is applied to a purely resistive circuit, the current flowing through the circuit is in phase with the voltage. This means that both the voltage and current reach their maximum and minimum values simultaneously. The relationship between voltage and current can be described by Ohm's Law, where the current is directly proportional to the voltage and inversely proportional to the resistance. As a result, the power consumed in the circuit is constant and can be calculated using the formula ( P = V \times I ).
this is the amount of voltage a circuit can hold.
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.

Power Factor applies to all A.C.(alternating current) power supplies. It ma not be apparent when a purely resistive load is applied as this offers a PF of 1.0 but any other load type will have a power factor somewhere between 0.0 and 1.0.

The television runs on Direct current or DC. Though AC is applied, it is converted to DC and used by the television to operate.
When an alternating current is applied to the running windings of a split-phase electric motor, it creates a magnetic field that interacts with the rotor. This interaction generates torque, allowing the motor to start and run. The split-phase design utilizes two windings—one for starting and one for running—ensuring efficient operation and smooth acceleration. The phase difference between the currents in the two windings is essential for creating the necessary rotating magnetic field.
