When calculating the power of a pure resistive load, the voltage and current are in phase with each other and the power factor is _____.
A) one
B) two
C) three
D) four
Pure Resistive Load
An electrical load that has no capacitance or inductance, resulting in current and voltage being in phase.
Power Factor
A dimensionless number between 0 and 1 that measures the efficiency of an electrical system, calculated as the ratio of real power to apparent power.
Voltage
The electrical potential difference between two points in a circuit, measuring the energy required to move a unit charge between those points.

Final Answer :
A
Explanation :
In a pure resistive load, the voltage and current are in phase, meaning the angle between them is zero degrees. This results in a power factor of one, as power factor is defined as the cosine of the phase angle between voltage and current.
