The rate at which energy is transferred is called ' power '.

The unit of any kind of power ... electrical, mechanical,
hydro, etc. ... is the ' watt '.  1 watt is 1 joule per second.

Answer : (1) power , (2) watt.

Explanation :

(1) The rate at which energy is transferred is called power. It describes the rate at which work is done.

Mathematically, it is defined as :

\(power=\dfrac{work}{time}\)

or

\(P=\dfrac{W}{t}\)

So, the correct option is (A) " power ".

(2) The SI unit of electrical power is watt. 1 watt is defined as follows :

\(1\ watt=\dfrac{Joules}{sec}\)

Hence, the correct option is (A) " watt".
