A 5 ohm resistor a 15 ohm resistor and a unknown resistor, r, are connected as shown with a 15 volt source. The ammeter reads a current of 0.5 ampere.

Question

I got .1V by using ohm's law but I'm not sure if it's right

Answer 1

since we cannot see the diagram, you will have to describe the series/parallel connections.

Also, you have not asked a question. I assume you want the voltage drop across r.
