In order to find the force experienced by a current-carrying conductor,we can use Maxwell's corkscrew rule.

All the distribution circuits for domestic purposes are parallel connections.

Find the minimum rating of fuse that can be safely used on a line on which two $1.1 \, kW$ electric geysers are to run simultaneously. The supply voltage is $220 \, V$. (in $A$)

$A$ magnetic compass needle is placed in the plane of paper near point $A$ as shown in the figure. In which plane should a straight current-carrying conductor be placed so that it passes through $A$ and there is no change in the deflection of the compass? Under what condition is the deflection maximum and why?

Differentiate between overloading and short-circuiting.

In an electric motor,the direction of current in the loop reverses after every $........$ rotation.
