Q. By mistake a voltmeter is connected in series and an ammeter is connected in parallel with a resistance in an electrical circuit. What will happen to the instrument?
A) Voltmeter is damaged
B) Ammeter is damaged
C) Both are damaged
D) None is damaged
Explanation
(d) Due to high resistance of voltmeter, connected in series, the effective resistance of circuit will increase and hence the current in circuit will decrease. Due to which the ammeter and voltmeter will not be damaged.
