If the combination is connected to a battery of emf 20 V and negligible internal resistance, determine the current through each resistor, and the total current drawn from the battery.

Given, EMF of the battery E = 20Volt

Current flowing through 2 Ω resistor is given by

Current flowing through 4 Ω resistor is given by

Current flowing through 5 Ω resistor is given by

Current flowing through 2 Ω resistor is 10Ampere; 4 Ω resistor is 5Ampere and through 5 Ω resistor is 4Ampere respectively.
