Question

the two terminals are at the same potential because

Answer 1

SO WHEN +ve & -ve TERMINALS OF A BATTERY ARE CONNECTED BY A CONDUCTING WIRE , RESISTANCE OF WIRECAN'T HINDER VOLTAGE OF BATTERY. ... When you connect the two terminals of a battery through a wire, the wire burns and short circuit occurs because the load in the circuit is negligible considering If the battery is offgassing, the spark could ignite those gases causing an explosion. Connecting the negative terminal last prevents that spark from occurring. Since the negative terminal is not connected, a circuit won't be completed if the wrench touches both the positive terminal and the chassis at the same time. the wire.
