Draw a diagram of an electric circuit containing a cell, a key, an ammeter, a resistor of 2Omega in series with a combination of two resistor (4Omega each) in parallel and a voltmeter across the parallel combination. Will the potential defference across the 2 Omegaresistor be the sameas that across the parallel combination of 4 Omegaresistors ?Give the reason.

1.	Draw a diagram of an electric circuit containing a cell, a key, an ammeter, a resistor of 2Omega in series with a combination of two resistor (4Omega each) in parallel and a voltmeter across the parallel combination. Will the potential defference across the 2 Omegaresistor be the sameas that across the parallel combination of 4 Omegaresistors ?Give the reason.
Answer» Solution :If `R_p `is the effective resistance of two resistors of `4 Omega` each in PARALLEL,then `1/R_p = 1/4 + 1/4 + 2/4 + 1/2` `:. R_p= 2Omega` SINCE, the combined parallel resistance is ALSO `2 Omega`, the potential difference across `2 Omega`resistor will be the same as that across the parallel combination of two `4Omega` resistors.
