Sunil Batra Solutions for Chapter: Electricity, Exercise 1: Practice Exercise 1A

$2$ ampere of current is flowing through a wire. What is the amount of charge passing through it in $1$ minute? Also find the number of electrons passed through a cross-section of wire in this time.

Find the electric potential of a point if$2 \mathrm{J}$of work is done in bringing a charge of $0.2 \mathrm{C}$ from infinity to that point.

Find the potential difference between two points if $5 \mathrm{J}$ of work is done in moving a charge of $2 \mathrm{mC}$ from one point to another.

How many electrons should be removed from a conductor so that it acquires a positive charge of $3.5\times {10}^{-9} \mathrm{C}$?

An electric bulb draws a current of $0.5 \mathrm{A}$ for $10$ minutes. Calculate the amount of electric charge that flows through the circuit.
