Charge, current and time

1.   State an equation that links charge, current and time.

2.   Calculate the missing values in the table below.

 

3.   Calculate the total charge which flows through a lamp drawing 100 mA for 200 s.

4.   A current of 0·5 A flows through a circuit in a time of 10 s.

(a)   Calculate the total charge flowing through the circuit.

(b)   If a single electron carries a charge of 1·6 x 10^-19 C, how many electrons flowed through the circuit?

.     Calculate the current flowing if 30 C of charge flows through a component
in 10 s.
