## Homework Statement

In the circuit, find the value of V3 such that the current through the 10Ω resistor is zero.

## Homework Equations

V=IR

## The Attempt at a Solution

I am not sure how to apply Kirchoffs loop rule to this situation. If I want the current through the resistor to be zero then how do I apply kirchhoffs loop rule at junction A for current? I am trying to make a general statement such as I3=I1+I2...but if I3 is zero I1=I2? it makes little sense to me. any help would be greatly appreciated! thanks pf!
