Answer to Question #180626 in Physics for Vaneeza Mohsin

Question

The following readings are taken from the meters. Reading on the ammeter = 0.04 A Reading on the voltmeter V1 =1.2 V

Reading on the voltmeter V2 = 0.3 V

a) Calculate the value of the lost volts in the circuit.

Answer 1

If the e.m.f. of the circuit is 1.6V as in the circuit diagram for this problem, the value of the lost volts in the circuit is

$$\Delta V=\text{e.m.f.}-V_1-V_2=0.1\text{ V}.$$
