Vedclass · Answer

(A) According to Ohm's Law,the relationship between voltage $(V)$,current $(I)$,and resistance $(R)$ is given by the formula: $V = I 	imes R$.To find the resistance,we rearrange the formula as: $R = \frac{V}{I}$.Given values are: Voltage $(V)$ = $220\, V$ and Current $(I)$ = $20\, A$.Substituting these values into the formula: $R = \frac{220}{20} = 11\, \Omega$.Therefore,the resistance of the electric arc lamp is $11\, \Omega$.

What is the resistance of an electric arc lamp,if the lamp uses $20\, A$ when connected to a $220\, V$ line?
