Question

potential difference of a electric bulb is 12V . the current through the electric bulb is to 2A. find the Resistance ​

Answer 1

Answer:

V = IR

12V = 2A × R

R = 12/2 ohm

R = 6 ohm

Answer 2

Potential Difference ( V ) = 12 V

Electric Current ( I ) = 2 A

From Ohm's Law, V = I*R => R = V/I

R = V / I = 12/2 = 6 Volt/Ampere = 6 Ω

Hence, the resistance of the bulb is 6 Ω.
