I have a test tomorrow and i'm having trouble figuring out some of these review problems. Any help would be much appreciated!(adsbygoogle = window.adsbygoogle || []).push({});

1) Find the power dissipated by R3 in a series circuit with a 12V battery with 3 resistors. R1=45ohms R2=200ohms R3=700ohms

I also have a few questions where it asks you to find the potential difference between two points. For example, before and after a resistor in a circuit. How do i do this?

Thank you very much!
