If by mistake voltmeter is connected in series and ammeter in parallel then
Options
(a) both are damaged
(b) ammeter is damaged
(c) voltmeter is damaged
(d) none of these
Correct Answer:
none of these
Explanation:
A voltmeter is having a high resistance. If it is connected in series, current will not pass in the circuit. By connecting an ammeter in parallel, because of the shunt, very little current would have passed through an ammeter in series. When it is in parallel, most of the current will pass through the shunt. One tries to pass less current. Both will not be damaged, but both will not show correct readings.
