## Homework Statement

1) A circuit contains a 10V battery and three resistors in parallel. The resistors have values R1=10ohm, R2=40ohm, R3=50ohm. What is the voltage across each resistor?

2)This time, the 3 resistors in parallel have values R1=10ohm, R2=20ohm, R3=500ohm. The current flowing through R2=100mA. What is the current flowing through R1?

## Homework Equations

## The Attempt at a Solution

1) 10 V across each, because the voltage is the same across parallel resistors right?

2) I made a V-I-R chart. Since R2 has a current of 100mA and its resistance is 20ohm, then the voltage is 2.0V. Since the resistors are in parallel, the voltage is the same for R1.

So 2volts=I(10ohm)

I=200 mA is this correct?
