While performing an experiment to determine the equivalent resistance of two resistors connected in parallel, a student observes the pointer of voltmeter at position X when the key is 'off' and the same pointer at position Y when the key is 'on'.The correct voltmeter reading is :(1) 0.2 V(2) 2 V(3) 2.2 V(4) 1.8 V |
