Answer to Question #114495 in Physics for David Raheem

Question

Two resistors 2ohms and 4ohms are connected across the resistors to measure the voltage across the resistors
Sketch the circuit diagram

Answer 1

To measure the voltage across unknown combination of resistors r, one can use the following scheme. All you need to find the voltage then is to multiply the current by 6 ohms according to Ohm's law: V=6I.
