What will happen to the current in a circuit, if its resistance is doubled ?
If $4.8\, A$ current is passed through an electrical appliance, then the number of electrons passing through it in $1\, second$ will be $......$
A series circuit has only one conducting path for the electrons that move through it; a paralle circuit has multiple conducting paths.
State with the help of a circuit diagram an activity to find the resistance ${ }^{\prime} R^{\prime}$ of a given wire. A current of $0.2\, A$ passes through a resistor of $20 \Omega$. Find the potential difference across its ends.
A wire of resistance $5 \,ohm$ is bent in the form of a closed circle. What is the resistance between two points at the ends of any diameter of the circle?
