Three resistors having values of 4 Ω, 6 Ω, and 10 Ω are connected in parallel. This circuit is connected to a 12 V battery. What is the current in the 10 Ω resistor?

Answer 1

Voltage is the same in parallel, while current is the same in series. So since these three resistors are in parallel, they have the same voltage, which is the 12V battery. Using the equation V=IR, 12V=I*10Ω gives you a current of 1.2A.
