## Homework Statement

This was a diagram, so I will describe it as accurately as possible.

[Edit]:

12 Volts go through one 2 Ohm resistor which then proceeds through a set of resistors in parallel. One is 20 Ohms, the other two are 10 Ohms.

How much power is being dissipated by one of the 10 Ohm resistors?

Unknown: Current.

## Homework Equations

V = IR

P = V * A

1/R(Parallel-Equivelant) = Sum(1/R

_{n})

## The Attempt at a Solution

Can I calculate the Current after the first resistor using V = I * R ? If so, I know how to calculate the total resistance by using 1/R = Sum of (1/R

_{n}). Would the resistance of one resistor just be 1/R = 1/10 --> R = 10?

THanks for any help
