A Lamp's Resistance Calculation

What is the resistance of a lamp that draws a current of 20 A when connected to a 100 V source?

The resistance of the lamp can be calculated using the formula: R = V / I, where R is resistance, V is voltage, and I is current.

Calculation of Resistance

Given: Voltage (V) = 100 V, Current (I) = 20 A

Using the formula R = V / I:

R = 100 V / 20 A = 5 ohms

Therefore, the resistance of the lamp is 5 ohms.
