Question

A speaker system is plugged into a 100v socket and 2.5 a of current runs through. Find the power of the system

Answer 1

250 Watts

Step-by-step explanation:

Recall that the formula relating power, current and voltage is

P = IV, where,

P = power (we are asked to find this)

I = 2.5 A

V = 100 V

substituting the above values into the equation:

P = IV

= (2.5)(100)

= 250 Watts
