If Three resistors of `6Omega,9Omegaand21Omega` are connected in series to a 12 V battery, find
a] The total resistance of the circuit.
b] The current flowing through the circuit.
c] The potential difference across the `21Omega` resistor.

Text Solution

Verified by Experts

a] Total resistance = `6+9+21=36Omega`
b] Current = `V//R=12//36=0.33A`
c] P.D. across `21Omega=0.33xx21=7V`
