2. Homework Equations

v=IR

3. The Attempt at a Solution
I have tried finding the total resistance of the circuit and then applying ohms law. My answer is 0.65 Amps but thats incorrect.

Any help is much appreciated!

Hi qwerty2x! :wink:

Show us your full calculations, and then we can see what went wrong, and we'll know how to help! :smile:
 
Use the equivalent resistance formulas and then Ohm's Law

For two resistors in series [tex]R_{eq} = R_{1} + R_{2}[/tex]
For two resistors in parallel [tex]\frac{1}{R_{eq}} = \frac{1}{R_{1}} + \frac{1}{R_{2}}[/tex]

or two resistors in parallel simplified [tex]R_{eq} = \frac{R_{1}R_{2}}{R_{1}+R_{2}}}[/tex]

Hope this helps!
