The voltage at the terminals of the generator is 60 V, and the resistance of the external circuit is 5 times greater than the internal resistance. Determine the EMF of the generator

Given: U (voltage at the generator terminals) = 60 V; R (external circuit resistance) = 5r, where r is the internal resistance of the generator.

You can calculate the EMF of the generator using the formula: ε = U * (R + r) / R = U * (5r + r) / 5r = U * 6r / 5r = 6U / 5.

Determine the EMF of the generator: ε = 6 * 60/5 = 72 V.

Answer: The EMF of the generator is 72 V.
