Electric Current and Circuit

A copper rod of cross-sectional area $A$ carries a uniform current $I$ through it. At temperature $T$, if the volume charge density of the rod is $\rho$, how long will the charges take to travel a distance $d$?

In a current carrying conductor the motion of an electron is 

In an electric bulb filament, $0.5 \mathrm{A}$ current is passed for $10 \mathrm{minutes}$. Calculate the electric charge passing through the circuit.

A current of $0.5 \mathrm{A}$ is drawn by a filament of and electric bulb for $10$ minutes. The number of electrons flowing through the circuit are

One ampere is synonymous with

In a conducting wire, $15 \mathrm{C}$ charge flows in $5 \mathrm{s}$. The current flowing in the conductor is :

An electric lamp is marked 60 W. 240 V. If it operates at 200 V, the current through it will be

The wire having a black plastic covering is a

The wire having a red plastic covering is a

Electricians use rubber gloves while working because

Since the deflection amounts of the identical compasses found as shown above in the figure on the sides of the wires in the same medium over which I_1, I₂ and I₃, currents pass are equal, what is the relationship between the currents?

Wire X, Y and Z are lying in the same magnetic fields. As per information in the diagram predict the direction of force experiment by current carrying wire.

When the currents in the figure pass through the flexible K and L wires, what is the position of the wires?

The force between two parallel wires carrying current has been used to define

Conventionally, the direction of the current is taken as

If I is the current through a wire and e is the charge of electron, then the number of electrons in t seconds will be given by
