Homework Statement
A 48 V DC wind turbine is hooked up to charge a battery bank consisting of four 12 V batteries in series. The wind is not blowing, but the batteries must supply 2 loads. One is a light bulb, rated at 175 W at 48 V; the other is a heater, rated 1000 W at 48 V. The loads are in parallel. The batteries may be constant 12V voltage sources, with an internal series resistance of 0.05 ohm each. How much power is actually supplied to the loads?
(Ignore the effect of temperature on resistance of filament and heating Elements)
Homework Equations
I'm assuming ohms law but don't know where start
The Attempt at a Solution
I don't know where to start with this question or what variables I'm even solving for. Here is a diagram I drew of the circuit.
