What will happen to the voltage if a salt bridge is removed between the half cells?

Answer

Answer:

The purpose of a salt bridge is not to move electrons from the electrolyte, rather to maintain charge balance because the electrons are moving from one half cell to the other. The electrons flow from the anode to the cathode thus if a salt bridge is removed between the half cells,  Voltage becomes zero.
