Question

find the resistance of a bulb is a current of 0.5 ampere flows through it when a potential difference of 220v is applied​

Answer 1

Explanation:

I= 0.5 A

V=220v

R=?

V=IR

R=V/I

= 220/0.5

= 2200/5

= 440 ohm

I hope it will help you!

Answer 2

Answer:

Explanation:  

             V = 220 V  

               I = 0.5 A

V = RI

R = V/I

  = 220/0.5

  = 440 ohm
