$A$ $60\,W$ bulb carries a current of $0.5\,A$. The total charge passing through it in $1$ hour is ............ $C$.

Explain how electric current is formed. Give a suitable example.

The electric current in a wire varies with time as $i = (2 + 3t) \text{ A}$. Calculate the charge that passes through the cross-section of the wire in $10 \text{ s}$.

The current in a wire varies with time according to the relation $I = 4 + 2t$. The quantity of charge which has passed through a cross-section of the wire during the time $t = 2 \, s$ to $t = 6 \, s$ will be .............. $C$.

In a neon discharge tube,$2.9 \times 10^{18}$ $Ne^+$ ions move to the right each second,while $1.2 \times 10^{18}$ electrons move to the left per second. The electron charge is $1.6 \times 10^{-19} \, C$. The current in the discharge tube is:

Which of the following is a scalar quantity?
