How do you know positive and negative terminals?
Look for a + by the positive terminal and a - by the negative terminal, or red for positive, black for negative. Some batteries have the positive terminal protruding and the negative terminal flat. Or you can get a meter that will tell you which is which,
What happens when you inadvertanly crossed the positive battery terminal from a negative to a positive and a positive to a negative.?
What happens when you inadvertently crossed the positive battery terminal from a negative to a positive and a positive to a negative.?Read more: What_happens_when_you_inadvertanly_crossed_the_positive_battery_terminal_from_a_negative_to_a_positive_and_a_positive_to_a_negative.
Why is there a plus and minus of batteries?
plus is the positive terminal (cathode) minus is the negative terminal (anode)
How can you tell which is positive and which is negative on a speaker hookup?
Depending on colours of course black is usually negative and the other colour (generally red but depends) is positive. Get a D-cell Battery. Now get two pieces of speaker wire. hold one wire on the positive terminal of the battery and hold the other on the negative side of the battery. touch the wires to the positive and negative posts on the speaker. if the cone moves out ward the positive and negative are correct if it moves inward then the positive and negative are reversed (out of phase.) this simple test will allow you to see which terminal is which.

Is Voltage with respect to negative terminal taken as positive or negative?
im not sure how clearly your phrasing your question, but when dealing with circuits potential difference (voltage) is max, and at the positive terminal its zero. it decreases as you go around the circuit. hope this helps
When an ammeter is connected in a circuit which terminal of the battery must be connected to the positive terminal of the ammeter?
The positive terminal of the battery would be connected to the positive terminal of the ammeter. The load would then be connected between the two negative terminals, positive side of the load being connected to the negative side of the ammeter.
Is the positive terminal of an ammeter connected to the positive terminal of the energy source?
No. An ammeter is to be connected in series, between the device and the battery's positive output, Its NEGATIVE terminal (red lead) has to be connected to the POSITIVE of the battery. Its positive terminal (black lead) will then be connected to the device's positive terminal. (Connecting an ammeter in series with a power supply by itself may damage or destroy the meter.)Almost every single digital ammeter made will indicate reverse current, so the worst you might get is a displayed reading of a negative amperage if you connected it in reverse.(For an illustration, see the related link)

Do electrons flow from the positive to the negative terminal of a wet cell?
Electrons have a negative charge. For that reason, electrons will always flow in the opposite direction of the current, which flows from positive to negative. Electrons will therefore move from a negative terminal to a positive terminal when we look at the load on a cell. Within the cell, the electrons will flow from the positive terminal to the negative terminal.
Does energy flow through the negative or positive of a battery?
Energy flows from the negative terminal to the positive terminal of a battery.
What happens when you inadvertanly crossed the positive battery terminal from a negative to a positive and a positive to a negative.?

What is positive about batteries?
One terminal is positive and the other terminal is negative. The positive terminal is slightly larger.
What does the negative terminal of a battery have?
The negative terminal of a battery has a - sign and positive terminal has a + sign.
Does the positive end of a battery go to the positive or negative end of the terminal?
The positive end of a battery goes to the positive end of the terminal. In retro spec, the negative end of a battery goes to the negative end of the terminal.
What is the difference between a positive terminal and negative terminal of a battery?
The positive + terminal is slightly larger.
What is the positive terminal of a diode known as?
It is called the positive + terminal or post, just like you list. Electrons flow for the negative - to the + terminal contrary to popular belief.Another AnswerAs electrons flow through the external circuit from anode (negative terminal) to the cathode (positive terminal) , then the answer is 'cathode'.
How many terminal does a battery have?
Two. The positive terminal, and the negative.
