Circuits 4
Let RC = 50 Ω, RB = 61 Ω, RA = 70 Ω and the Potential Difference of the battery be 104 V
a.Given the circuit above find the potential difference across and Current through each resistor.

b. How much Power is Resistor B using?  Watts

c. How much Power is the Whole circuit using?  Watts
d.RA is a variable transistor that can be adjusted between 50 Ω and 100 Ω. What should the A be adjusted to if you want the Voltage across C to be exactly 26V?
