Problem

A two-loop circuit contains: • Left loop: a

10\,\text{V}

ideal battery and a

2\,\Omega

resistor. • Right loop: a

5\,\text{V}

ideal battery whose polarity opposes the

10\,\text{V}

source, and a

1\,\Omega

resistor. • The junction of the two loops is connected by a

3\,\Omega

resistor. Determine the electrical power supplied by the

10\,\text{V}

battery. a)

25\,\text{W}

-50\,\text{W}

(battery absorbs power) c)

50\,\text{W}

22.7\,\text{W}

\;(approx.)
