Question

What potential difference is required to produce a current of 0.5 A in a bulb of power 60 W​

Answer 1

V=P/I

V=60/0.5

V=120

Explanaton:

the formula P=IV is converted to V=P/I to make V (voltage) the subject. then sub in the values to get your answer

note that potential difference is same as voltage

Answer 2

ans is 120

Step-by-step explanation:

I= 0.5 A

p= 60w

p=Iv

60/0.5

v= 120
