A salt bridge is a device used in an electrochemical cell for connecting its oxidation and reduction half cells wherein a weak electrolyte is used. In other words, a salt bridge is a junction that connects the anodic and cathodic compartments in a cell or electrolytic solution. The salt bridge usually consists of a strong electrolyte which is further made up of ions.

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. Without the salt bridge, the solution in the anode compartment would become positively charged and the solution in the cathode compartment would become negatively charged,because of the charge imbalance,the electrode.
Notice that anode has a (+) polarity and cathode has (—) polarity in an electrolytic cell, where external current is applied.

The scope method to measure capacitor esr is a qualitative measurement. It gives you an order of magnitude, but it is not a precise measurement. An lcr (inductor, capacitor, resistor) bridge uses techniques, like a bridge, to measure the esr, so it is far more accurate. However, to validate if a capacitor is “good” or not, the scope works okay.
