Homework Statement



How would you calculate the voltage at a specific resistor given that it's a parallel circuit.

Hi Gardalay! Welcome to PF! :smile:

Use Kirchhoff's rules to find the current through it, and then use Ohm's law :wink:

(but what exactly is the question?)
 
If the 25ohm resistor in figure19-39 were shorted out, what then would be the current through the 10ohm resistor?

Call the currents through each section i1 i2 i3 etc, and apply Kirchhoff's rules …

what do you get? :smile:
 
I got 7.14amps with the 25ohm resistor and 6.9amps without the 25ohm resistor.
 
Show your calculations if you want us to check them! :smile:
 
ok, i finally got this figured out, thanks for the help
