Draw a circuit diagram of an electric circuit containing a cell, a key, an ammeter, a resistor of \(2\ Ω\) in series with a combination of two resistors (\(4\ Ω\) each) in parallel and a voltmeter across the parallel combination. Will the potential difference across the \(2\ Ω\) resistor be the same as that across the parallel combination of \(4\ Ω\) resistors? Give reason.
Total resistance for the parallel combination is
The resistance of resistors in parallel combination is resistance of series resistor. Hence, the potential difference across \(2\ Ω\) resistance is the as potential difference across the other two parallel resistors.
