Problem

In the circuit, the left loop contains an 18 V18\,\text{V} battery and a 3 Ω3\,\Omega resistor in series; the right loop contains a 10 V10\,\text{V} battery and a 5 Ω5\,\Omega resistor in series. The two loops share a common 2 Ω2\,\Omega resistor. All batteries have negligible internal resistance, and both are oriented with their positive terminals at the top of the circuit. Determine the power supplied by the 18 V18\,\text{V} battery. (a) 50 W50\,\text{W} (b) 95 W95\,\text{W} (c) 85 W85\,\text{W} (d) 65 W65\,\text{W}
