    I am a high school student struggling with series parallel circuits please help with this question and explain how to break down. I will try my best to show problem

    Code ( (Unknown Language)):

    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).

    thw 10 watt 120 volt lamp should be in the rear between arrows. this circuit is 120 volts

    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.
