Question

If a lamp has a power of 24W when connected to a 12 V supply, what is the current in it?

Answer 1

by finding the power in the circuit we must know current I and voltage V

Step-by-step explanation:

P=VI

BY ANY TWO QUANTITIES WE GET THE THIRD

I=P/V

=24/12

I=2A (unit)

Answer 2

2A

Step-by-step explanation:

P=IV

24W = I x 12V

I = 24W/12V

I= 2A
