Consider this circuit with R1 = 30 ohm, R2 = 10 ohm, R3 = 10 ohm, R4 = 20 ohm,(adsbygoogle = window.adsbygoogle || []).push({});

R5 = 60 ohm. (the circuit is attached)

A. What is the current across the resistor R2, if a voltage of 110 Volt is applied to

the two terminals at the bottom of the figure?

B. What is the voltage drop across R2?

C. Keep all other resistances at the same value, but allow R2 to vary. What are the

minimum and maximum resistances that this circuit can have?

I know that i have to use V=IR to solve for the voltage drop and the current across the resistor.

I have already found the equivilent resistance of the arrangement. I am able to find the total current throughout the whole circuit, but after that I don't really know where to start.
