The current in a wire is one ampere . Explain this statement in terms of the charge flowing through the wire.

Current through a wire decreases from 4 A to zero in 10sec. Calculate charge flown through the wire du ring this interval of time.

Electric current in a wire is time rate of flow of charge. The charge in coulombs that passes through a wire after t seconds is given by the function q(t)=t^(2)-2t^(2)+5t+2 . Determine the average current (in coulmbe per second) during the first two seconds.

The current through a wire depends on time as i=(2+3t)A . Calculate the charge crossed through a cross section of the wire in 10sec.

2 A electric current is passed for 1 minute through a conducting wire. How much electric charge will pass through this wire?

The resistance of a conducting wire is 10 Omega . If a battery of 1.5 V is connected to it, the electric current flowing through it will be ………………….. .

Define SI unit of electric charge in terms of Ampere.

A compass needle is placed near a current - carrying straight wire . State your observation for the following case and give reason for the same in each case : (1) Direction of electric current in the wire is increased . (2) Magnitude of electric current in the wire is increased . (3) Teh compass needle is displaced away from the straight wire .

Two wires of same material having lengths and radii in the ratio of 3 : 4 and 3 : 2 respectively are connected in parallel with a potential source of 6V. the ratio of currents flowing through them I_(1) : I_(2) = ..... .

Consider a wire carrying a steady current, I placed in a uniform magnetic field vecB perpendicular to its length. Consider the charges inside the wire. It is known that magnetic forces do no work. This implies that,
