A 10ohm resistor is attached to a 20ohm resistor in series. This combination is then attached to a 30ohm resistor in parallel. This is then connected to a 120V battery. What is the current drawn from the battery?

you have two 30 ohms in parallel, total effective resistance 15 ohms, in a 120 battery (wow), current=120/15 amps

A 10ohm resistor is attached to a 20ohm resistor in series. This combination is then attached to a 30ohm resistor in parallel. This is then connected to a 6V battery. What is the current drawn from the battery?
