Answer to Question #208647 in Electric Circuits for Ben

Question

find the voltage at point c in the following circuit. the voltage drop Vcd is 3.5 V.

Answer 1

Gives

$V_{CD}=3.5V$

The potential at the points a and b is 9.0. If

the voltage drop across cd is 3.5 V, and the

potential at d = 0.

∴ The potential at c must be 3.5 V.(Because

this is how much it has to lose to get to zero at

d).
