Consider the given circuit and find the current flowing in the circuit and potential difference

Electricity (10)

Consider the given circuit and find the current flowing in the circuit and potential difference across the 15 Ω resistor when the circuit is closed. 

Answer

Total resistance of the circuit =

R = R1 + R2 + R3 = 5 + 10 + 15 = 30 ohm

Potential difference across the circuit / By ohm’s law

Potential difference across 15 ohm Resistor = 1A X 15 ohm = 15 volt
