Question

what is the resistance of a filament lamp wjen a voltage of 3 V across it causes a current of 0.5 A?​

Answer 1

Voltage=3

Current=0.5

R=V/I

R=3/0.5=6

I hope this helps ( ╹▽╹ )

Answer 2

Answer:

Firstly write the things that are given :

Potential difference = 3 volt

Current = 0.5 ampere

Explanation:

By using Ohm's law, we can find out the solution of this numerical

V = I * R

3 volt = 0.5 ampere * R

formula to calculate resistance is R = V / I

R = 3 volt / 0.5 ampere

R = 6 ohm
