For a heater rated at $$4 \  kW$$; $$220 \  V$$ . Calculate the resistance of the heater element.

A $$10\ k\Omega$$ resistor can be obtained by using

For a metallic wire, the ratio $$\displaystyle \frac{V}{i}$$ (where, V = applied potential difference and i = current flowing)

An experiment to verify ohm's law, a conductor of resistance R is taken. During the experiment, temperature of the conductor increases with the flow of current. Resistance of the conductor will
