A galvanometer acting as a voltmeter will have
Options
(a) A high resistance in parallel with its coil (b) A high resistance in series with its coil (c) A low resistance in parallel […]
A galvanometer of 50 Ω resistance has 25 divisions. A current of 4×10⁻⁴ A gives a deflection of one division. To convert this galvanometer into a voltmeter having a range of 25 volt, it should […]
A coil of 40 henry inductance is connected in series with a resistance of 8 ohm and of a 2 volt battery. The time constant of the circuit is
Options
(a) 5 sec […]
A 6 volt battery is connected to the terminals of a three metre long wire of uniform thickness and resistance of 100 ohm. The difference of potential between two points on the wire separated by […]
