The unit of electric current,$.......$,is also called an ampere,named after André-Marie Ampère.

The flow of charge through a conducting wire connected to a cell is the result of chemical reaction inside the cell.

Which alloy is used to make the heating element (resistance wire) in an electric iron?

The resistance of a conducting wire is $10\, \Omega$. If a battery of $1.5\, V$ is connected to it,then how much electric current will flow through it (in $, mA$)?

What will be the equivalent resistance between points $A$ and $B$ of the following electric circuit?

$(a)$ Derive the formula for the calculation of work done when current flows through a resistor.
$(b)$ One electric bulb is rated $40 \ W$ and $240 \ V$ and another is $25 \ W$ and $240 \ V$. Which bulb has higher resistance and how many times?
