When a 26.0-V emf device is placed across two resistors in series, a current of 11.0 A is flowing in each of the resistors. When the same emf device is placed across the same two resistors in parallel, the current through the emf device is 59.0 A. What is the magnitude of the larger of the two resistances?

Expert Solution

Let the resistors be

Given that when a 26.0-V emf device is placed across the two resistors connected in series, a current of 11.0 A is flowing in each of the resistors.

In series connection, current across all devices is the

So total current,

Equivalent resistance,
