A 10-ohm resistor is attached to a 20-ohm resistor in series. This combination is then attached to a 30-ohm resistor in parallel. This is then connected to a 120-V 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 10-ohm resistor is attached to a 20-ohm resistor in series. This combination is then attached to a 30-ohm resistor in parallel. This is then connected to a 6-V battery. What is the current drawn from the battery?
