R P Goyal and S P Tripathi Solutions for Chapter: Current Electricity, Exercise 1: EXERCISE–8(A)

Distinguish between a closed circuit and an open circuit, with the use of suitable labelled diagrams.

Write the condition required for a circuit to be a closed circuit.

A cell is used to :

The unit of current is :

The insulator of electricity is :

A charge $0.5 \mathrm{C}$ passes through a cross section of a conductor in $5 \mathrm{s}$. Find the current.

A current of $1.5 \mathrm{A}$ flows through a conductor for $2.0 \mathrm{s}$. What amount of charge passes through the conductor?

When starter motor of a car is switched on for $0.8 \mathrm{s}$, a charge $24 \mathrm{C}$ passes through the coil of the motor. Calculate the current in the coil.
