Question

Watt, which is a unit of power, is equal to ____ a) a joule divided by a second b) a joule times a meter c) a joule times a second d) a joule divided by a meter

Answer 1

Power is the RATE of use, flow, or transfer of energy.

1 watt = 1 joule PER SECOND.

The correct choice is ' a '.

Answer 2

Answer: Watt, a unit of power is equal to a joule divided by a second

Step-by-step explanation:

Power is defined as the ratio of rate of work done by an object. It is measured in Watt.

Mathematically,

`P=(W)/(t)`

where,

W = work done by the object. It is measured in Joules

t = time taken by the object. It is measured in seconds

So, the unit of watt is equal to a joule divided by a second.

Hence, Watt, a unit of power is equal to a joule divided by a second
