sorry bad diagram but cant copy paste. this is a circuit the v indicates arrows continuing the circuit. 1 branch has 2 10 ohm resistors. the other main circuit has a 30 ohm resistor and a 10 watt 120volt lamp. Please help answer. im pretty sure the formula is 1 over, 1 over R1 + 1 over R2 + 1 over R3 but im lost for some reason.
Question.
When current is flowing through the 10-ohm resistors, the voltmeter reading will be:(since its hard to show the volt meter is placed across the bottom 10 ohm resistor).

If I could understand the circuit I would try to help but the description of the circuit is not clear enough and the picture is too messed up.
