I need to find out how to find the expected voltage of a circuit?

Question

I have a rectangular circuit with a voltage source of 12 volts on the left side of the rectangle. on the right side of the rectangle i have two 10 Megaohm Resistors one on top of the other in series. I need to find the expected voltage across the bottom resistor as the voltage is flowing clockwise.

Answer 1

Mike is correct -- if they are the same resistance, the voltage divides in two.

The formula for finding the voltage for different values is:

R1 is the top resistor

R2 is the bottom resistor

V across R2 = Vsource * (R2 / (R1 + R2) )

check:

V = 12 * 10Meg / (10Meg + 10 Meg)

V = 12 * 10Meg / 20Meg

V = 12 * 1/2

V = 6

.

Answer 2

if both resistors are in series, and they are of the same value, the voltage will be 6 volts each.
