The given circuit,Now we'll be assuming the battery is an ideal voltage source with zero internal resistance and it allows ANY amount of current to pass through it.So, the circuit may be rewritten for current analysis as,As two resistors are in parallel and of same magnitude, the current division will be equal, i.e., each resistor will have 2A/2 = 1A current flowing through.Therefore, the voltage drop across any of the resistor is,
