In the circuit shown in the figure, two resistors `R_(1) and R_(2)` have been connected in series to an ideal cell. When a voltmeter is connected across `R_(1)` its reading is `V_(1) = 4.0` volt and when the same voltmeter is connected across `R_(2)` its reading is `V_(2) = 6.0` volt. The reading of the voltmeter when it is connected across the cell is `V_(3) = 12.0` volt. Find the actual across `R_(1)` in the circuit.
