If resistors are connected in parallel,the voltage across each remains the same.

Which symbol is used for the resistivity of a conductor?

Insulators like wood and rubber have a very low electrical resistance.

In the circuit diagram shown,the two resistance wires $A$ and $B$ are of the same area of cross-section and same material,but $A$ is longer than $B$. Which ammeter,$A_{1}$ or $A_{2}$,will indicate a higher reading for current? Give a reason.

If $10$ bulbs of $100 \ W$ each are kept on for $1 \ \text{hour}$, how much electrical energy is consumed?

What type of electric charge does a proton possess?
