A) \[\frac{1}{10}\] ampere
B) \[\frac{3}{10}\] ampere
C) \[\frac{4}{10}\]ampere
D) None of these
Correct Answer: D
Solution :
The voltage across each lamp is \[220V\] and the resistance of each lamp is \[2200\] ohm. Current drawn by each lamp\[=\frac{220}{2200}=\frac{1}{10}Amp\]. Ammeter records the sum of currents of the \[5\] lamps behind it, which while returning meet at the node to which the ammeter is connected. So, reading of the ammeter \[=\frac{5}{10}\] Amp.You need to login to perform this action.
