If a voltmeter has one black and two red terminals how should it be connected?
The black terminal is typically connected to the negative terminal on the circuit, while one of the red terminals is connected to the positive terminal. The other red terminal is used to measure the voltage across the circuit by placing it in parallel with the component or point where you want to measure the voltage.
What polarities red wires and black wires indicates in case of dc measurement?
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.
I have a red green and black wire and TV terminals marked 1 2 and 3 Which goes to which?

What are the wire connections to a L14-20P plug?
A L14-20P is a 3 pole 4wire 125/250 volt grounding plug. The four wire (white, red, black and green) cable connection will be, white wire to the W terminal, red to the X terminal, black to the Y terminal and green to the G terminal. The X and Y terminals wires (red and black) can be interchanged so that there is no cross over of the conductors as they protrude from the cable jacket.

How do you jump start a car, and should the red or black cable be connected first?
To jump start a car, first connect the red positive cable to the positive terminal of the dead battery, then connect the other end of the red cable to the positive terminal of the working battery. Next, connect the black negative cable to the negative terminal of the working battery, and finally connect the other end of the black cable to a metal surface on the car with the dead battery, away from the battery. Start the working car and let it run for a few minutes before attempting to start the dead car. The red cable should be connected first.
