What happens to the voltage across resistor, Physics

Assignment Help:

A seat of EMF is in sequence with a resistor R1 and with a parallel combination of two other resistors R2 and R3. R2 is a changeable resistor whose resistance can be changed just by turning a knob. As the knob is turned to raise the resistance of R2 what happens to the voltage across R3?
