(Answered) In the circuit shown the current through the 12 v battery

Academics

In the circuit shown, the current through the 12 V Battery is measured to be 70.6 mA in the direction shown.

a) What is the current through the 24V source?

b) What is the potential difference between points a and b?

c) How much power is dissipated on the 20 ohm resistor?

d) What is the current through the 30 ohm resistor?

e) The internal resistances are made of 5 m long wire with a diameter of 100 micrometers. What is the wires resistivity(value and units)?

Note: This is not a homework problem, I am trying to study for an exam. Doing problems that include everything in them is the best way for me to learn the material, but I dont know if I am right or not when I am finished. I am using Brainmass to help me here.
