## Homework Statement

2. Homework Equations [/B]

## V = IR ##

## The Attempt at a Solution

My solution:

R1,R2,R3 are in parallel and so we can find their total R

## \frac {R1×R2×R3}{R1+R2+R3} = R'##

##R' = \frac {10}{3}##

R' is in series with R4

## ∴ R= R' + R4 = \frac{10}{3} +10 = \frac{40}{3}\Omega ##

We find current to be ,

$$I=\frac{3}{4} A ------(From ~Ohm's~ Law)$$

## V ~across~ R1,R2,R3 ~is~ same ~and ~I~ across ~R'~ and ~R ~is ~same##

$$∴ V'=I×R'=\frac{3}{4}×\frac{10}{3}=\frac {5}{2}$$

Similarly, we find for the other.

Is my process alright ?
