Question

A current of 0.3 amperes is drawn by the filament of an electric bulb for 2 minutes. Find the amount of electric charge that flows through the circuit. (use Q = It formula, 't' should be in second)​

Answer 1

Given that :- Current ( I ) $=0.5 A$

                      Time ( t ) $=2 minutes$

As we have to find amount of electric charge that flows through the circuit,

By converting the given time in minutes into seconds we get,

Time ( t ) $=2$ × $60=120 sec$

$Q = It$

$Q=0.3$ × $120$

$Q=36 C$

Thus, the amount of electric charge that flows through the circuit is $36 C$.
