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.

Explanation

In series combination of resistors, voltage across each resistor will proportional to its resistance. Equivalent resistance of parallel combination of `4Omega` resistors is `2Omega`. Hence the voltage drop across `2Omega` resistor and the parallel combination of `4Omega` resistors will be the same.
