<p>Draw a circuit diagram of an electric circuit containing a cell, a key, an ammeter, a resistor of 2<math xmlns="http://www.w3.org/1998/Math/MathML"><mi>&#937;</mi></math>&nbsp;in series with a combination of two resistors ( 4<math xmlns="http://www.w3.org/1998/Math/MathML"><mi>&#937;</mi></math>&nbsp;each) in parallel and a voltmeter across the parallel combination. Will the potential difference across the 2<math xmlns="http://www.w3.org/1998/Math/MathML"><mi>&#937;</mi></math>&nbsp;resistor be the same as that across the parallel combination of 4<math xmlns="http://www.w3.org/1998/Math/MathML"><mi>&#937;</mi></math>&nbsp;resistors? Give reason.</p>
