Question

The power on any voltage rail of the hard drive is calculated by multiplying _____. (a). Voltage X Current (b). Voltage X Watts (c). Current X Watts (d). Voltage X Frequency

Answer 1

Answer:

(a). Voltage X Current

Explanation:

Power -

In the concept of physics , power is denoted by P ,

Power = Voltage * Current

Power = V * I

The unit is Ampere  *  Voltage

Power is defined as the rate of work done , i.e. , work divided by time .

Power = work / time .

Power is a scalar quantity .

The standard unit of power is Watt , which is denoted by W .
