Given\: - \:\: \\            => Current(A) \: = 10A \\ => Potential \: Difference \: = \: 220V \\
___________________________

To \: find \: - \: Resistance(Ohm) \: =\:?
___________________________

 \\Solution \: - \: We \: know \: that \\ \\ V = IR \:\:\:\:(Ohms \: law) \\\\ R = \frac{V}{I} \: \: (after \: rearrnging \: it) \\\\ => R = \frac{220}{10}\bf \\ => R = 22 \: Ohms

• Hence, the Bulb has a \bf\textit{\underline{Resistance}} of 10 Ohms.
