## Homework Statement

Hi there, I just want to see if I am doing these questions correctly. Any help with this would be great. The question and circuit diagram are in the attachment. Cheers

## Homework Equations

Kirchoff's Laws for voltage and current. I'm not too sure if there is an equation, you just have to remember that the total current in a node is the same as the input. And for a loop, the total voltage drop = 0.

## The Attempt at a Solution

I said that for loop one, on the left:

60=I

_{1}20 + I

_{2}10

For loop two, since the two 20 ohm resistors are effectively one 10 ohm resisitor:

20=I

_{2}20 + I

_{1}10

Subing I

_{2}into the first equation, you get an answer of 1.75A for I

_{1}

which gives I

_{2}=2.5A

Hence a current of

**and voltage of**

__4.25A__

__43.75V__#### Attachments
