A milliammeter with a current sensitivity of 1mA per division is utilised as a voltmeter. Determine the voltage per division of this instrument if its resistance is made `500Omega`

It is required to measure the resistance of a circuit operating at 120 V . There is only one galvanometer of current sensitivity 10^(-6) A per division. How should the galvanometer be connected in the circuit to operate an ohmmeter? Why minimum resistance can be measured with such a galvanometer if its full-scale has 40 divisions?

It is required to measure the resistance ofa circuit operating at 120V. There is only one galvanometer of current sensitivity 10^(-6) A per division. How should the galvanometer be connected in the circuit to operate as an ohmmeter? What minimum resistance can be measured with such a galvanometer if its full scale has 40 division? Construct the entire scale of such an ohmmeter in ohms per 5 division? Neglect galvanometer resistance.

A galvanometer has a current sensitivity of 5 divisions per milliampere and voltage sensitivity of 1 division per millivolt. The galvanometer has 30 divisions and it is to be used as an ammeter to read 6 A. This requires a shunt of value

A galvanometer has a current sensitivity of 4 div/microampere. If the resistance of the galvanometer is 100 Omega , its voltage sensitivitiy will be
