Question

What will happen if voltmeter is connected in series?
What will happen if ammeter is connected in parallel?
Plz explain

Answer 1

if ammeter is connected in parallel the ammeter will burn if the amount of current is high. if the current is low then the ammeter will for show the current flowing in the circuit. It leads to short circuit!!!

if the voltometer is connected in parallel the reading of the meter is zero as it has very high resistance. No deflection occurs.

Answer 2

Voltmeter has very high resistance to ensure that it's connection do not alter flow of current in the circuit.Now if it is connected in series then no current will be there in the circuit due to it's high resistance. Hence it is connected in parallel to the load across which potential difference is to be measured.
