Given a DC voltmeter has a sensitivity of 500ohm/V. For a full scale reading in 100V range, what will be the current through voltmeter?
Given a DC voltmeter has a sensitivity of 500ohm/V. For a full scale reading in 100V range, what will be the current through voltmeter? Correct Answer 200mA
Full scale reading in 100V range means 100V itself. For a sensitivity of 500ohm/V current through it will be the ratio of scale reading and sensitivity. ie, 0.2A=200mA.
