## Homework Statement

In a circuit consisting of both parallel and series arrangement, how do you find the potential difference of X(in red) and Y(in blue)? and how did you derive at those answers?

## Homework Equations

idk

## The Attempt at a Solution

total resistance=4 ohms +(1/r eff=1/2ohms+1/4ohms)

=4ohms+4/3ohms

=5 1/3 ohms

current=16 divide by 5 1/3ohms

=3 ampere

**potential diff for X ------V=RI**

**=(1/2)(3)**

**=1.5**

**potential diff for Y-------V=RI**

**=(1/4)(3)**

**= 3/4**

**I WAS TOLD THOSE IN RED ARE WRONG. BUT WHY? I DIDN'T SEE ANY MISTAKE IN CALCULATION.**

**can someone help me please? please explain to me what went wrong thanks**
