Question

If the potential difference across an electric bulb is 4.6v and the current flowing through it is 0.25a, what is the resistance of the bulb

Answer 1

Answer: According to Ohm's Law

V=I/R

R=V/I

V is denoted for potential difference

I is denoted for Current

R is denoted for Resistance

R= 4.6/0.25

R= 18.4
