What will be the length and diameter of a certain piece of copper, if it is to be shaped into a conductor of minimum resistance?

The resistance of a conductor does NOT depend on

The difference between the maximum and minimum values of resistance of a resistor with the color scheme green-green-red-silver is

What will be the resistance of a wire at 0 degree celsius, if its resistance is $5\mathrm{ohm}$ at $50$ degree celsius and $6\mathrm{ohm}$ at $100$ degree celsius?

The resistance of the platinum wire of a platinum resistance thermometer at the ice point is $5 \mathrm{\Omega }$ and at steam point is $5.23 \mathrm{\Omega }$. When the thermometer is inserted in a hot bath, the resistance of the platinum wire will be $5.795 \mathrm{\Omega }$. Calculate the temperature of the bath.

What will be the maximum number of $60 \mathrm{W}$ bulbs in parallel that can be turned on when a house wiring supplied with a $220 \mathrm{V}$ supply line is protected by a $6$ ampere fuse?

An electric bulb is rated $220 \mathrm{V}$ and $100 \mathrm{W}$. What is the power consumed by it when operated on $110 \mathrm{V}?$

A galvanometer can work as a voltmeter by connecting
