Answer:
An electric lamp, whose resistance is 20 Ω, and a conductor of 4 Ω resistance are connected to a 6 V battery. Calculate (a) the total resistance of the circuit, (b) the current through the circuit, and (c) the potential difference across the electric lamp and conductor. = 24 Ω. ... V1 = IR1 = 0.25 A x 20 Ω = 5 V.
