Detailed Solution

The electrode in a voltameter that is connected to the -ve terminal of a battery is the cathode.
A voltameter is an apparatus used for measuring the quantity of electricity passed through a conductor by the amount of electrolysis produced. Anode and cathode are the two electrodes used in electrolysis for the chemical reaction. A negative electrode is next to a positive electrode. The positive electrode is an anode, and the negative electrode is a cathode. Therefore, it is necessary to connect the battery's positive terminal to the positive electrode and its negative terminal to the negative electrode. The negative terminal is thus connected to the cathode.
