What is the resistance of ideal voltmeter ? How much work is done in moving a charge of 4 C from a point of220 V to another point of 230 V? |

Answer» The internal resistance of an ideal voltmeter is infinity and the internal resistance of an ideal ammeter is zero.Ammeter is connected in series and voltmeter is connected in parallel with the electric appliance. here we have Q(charge) = 4 coulomb V(potential difference)= 230V - 220V = 10V we want work done so by using W = VQ W= 4 into 10 W = 40 j hit like if you find it useful |
