Study the following circuit and answer any four questions given below: Find the potential difference across 4 Omega resistor.

Draw a circuit diagram of an electric circuit containing a cell, a key, an ammeter, a resistor of 2Omega in series with a combination of two resistors [ 4Omega each] in parallel and a voltmeter across the parallel combination. Will the potential difference across the 2Omega resistor be the same as that across the parallel combination of 4Omega resistors? Give reason.
