Question

find the resistance of a bulb having a current of 0.5A connected across a battery of 12V​

Answer 1

Answer:

Use formula

R=V/i

Put the value then you get the answer

Answer 2

Answer:

I = 0.5A

= 5 × 10^-1A

V = 12V

R = ?

from ohm's law :-

V = IR

12 = 5 × 10^-1 × R

12 / 5 × 10^-1 = R

12×10^1 / 5 = R

120 / 5 = R

24ohm = R
