Find the current flowing through the circuit.
Amps=Total Voltage / Total Resistance
The Attempt at a Solution
(20 + 12 + 12 + 3) / (10 + 5 + 30 + 40 + 20 + 15)=0.39A
I'm almost certain that this is wrong. I don't even know if the formula I used is actually valid. Any help you can provide would be greatly appreciated.
On an unrelated note, has anyone seen a good explanation of the right-hand rule (for magnetic fields)?
