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

Explanation

The required circuit diagram is shown in (Fig. 3.45). Since the resistance of parallel combination of two resistors (`4 Omega` each) is also `2 Omega`, the pd across `2 Omega` resistor is the same as that across the parallel combination.
