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.

1.	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.
Answer» SOLUTION : 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.
