Voltage=3
Current=0.5
R=V/I
R=3/0.5=6
I hope this helps ( ╹▽╹ )

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
