In a 48V DC system you ground the positive to 0V so the live wire will be -48V.
Yes, that is correct.
You should be asking, 'What is the potential reading of a positive wire....?', as 'voltage' means 'potential difference' and you can't have a potential difference on a wire! The positive wire has a potential difference of +110 V with respect to the negative wire.
No, positive wire and hot wire are not the same. Positive wire typically refers to the wire carrying positive voltage in a DC circuit, while hot wire usually refers to the wire carrying current in an AC circuit. The terms are specific to different types of electrical systems.
In DC measurements, the red wire typically indicates the positive polarity (+) while the black wire indicates the negative polarity (-). It's important to connect the red wire to the positive terminal and the black wire to the negative terminal when taking measurements to ensure accuracy and avoid damaging the equipment.

In most circuits, the wire that isÊ"dashed" on a wiring diagram is positive. The other wire, often unmarked, is the negative one.
In a DC circuit Red is positive and Black is negative. In AC systems White is neutral and Ground is green or green-yellow stripe.
If there is only one wire connection on the electric choke then that wire needs to be a positive wire. You will want to run one that only has voltage when you turn on the key. If it has two connections, one is positive and one is ground. Same thing as the positive connection on the single wire type....then simply run the other terminal to a good ground.
YesCaveatIn general, when working with DC, the red wire is positive and the black wire is negative. In the US and Canada, when working with AC, the colored wires (red, black...) are "hot", the white wire is neutral and the green or bare wire is ground.Note that the above is NOT a requirement for "switch legs".
In a DC circuit it is positive. In a 220v ac circuit it's one of the two positive (hot) lines.
Direct current (DC) refers to electric current where electrons always flow in the same direction in the wire. This is in contrast to alternating current (AC), where the flow of electrons periodically reverses direction. DC is commonly used in batteries and electronic devices that require steady and constant voltage.
