Homework Help: physics.

Posted by Nilan - please help on Wednesday, May 18, 2011 at 7:44pm.

resistors of 30 ohms and 60 ohms are connected in parallel and joined in series to a 10 ohm resistor. the circuit voltage is 180 volts
I need to find
1)the voltage of the parallel circuit
2)the resistance of the complete circuit
3)the voltage across the 10 ohm resistor
4) the voltage across the parallel circuit
5) the current through the 10 ohm resistor
6) the current through the 30 ohm resistor
7) the current through the 60 ohm resistor

Can you please help with the formulas and how to set up the problem?
Thank you
