What is your question?
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.

When the switch is closed in a simple circuit, the negative charges (electrons) flow from the negative terminal of the battery through the circuit and back to the positive terminal. This flow of electrons creates an electric current that powers the circuit components.
pretty simple. on the back of the lighter there are 2 connections one is labled positive, the other is labeled negative. Wire the Positive connector to the Positive terminal on your main battery, and the Negative conector to the Negative terminal on your battery. Easy as pie, 99.9% of 12V lighters already have a fuse in them so no need to worry about inline fuses.
To determine which speaker wire is positive and which is negative, you can use a simple method involving a battery. Connect the two wires to a small battery (like a 9V battery) briefly; if the speaker cone moves outward, the wire connected to the positive terminal of the battery is the positive wire. If it moves inward, the wire connected to the negative terminal is the positive wire. Be cautious not to leave the wires connected for too long to avoid damaging the speaker.
i dunno if this is the answer youre looking for. negative x negative = positive negative x positive = negative positive x positive = positive same thing with dividing integers its really simple.
A simple one would.
In a simple flashlight circuit, electrons flow from the negative terminal of the battery, through the circuit (which typically includes a switch and light bulb), and return to the positive terminal of the battery. This flow of electrons creates a current that powers the light bulb and produces light.
The author suggests using the mnemonic "Red before Black," which indicates that you should connect the positive (red) clamp to the positive terminal of the battery first, followed by the negative (black) clamp to the negative terminal. This simple phrase helps reinforce the correct order of connections, ensuring safety and preventing potential sparks or accidents during the jump-starting process.
In a simple flashlight circuit, electrons flow from the negative terminal of the battery through the metal conductor to the light bulb, where they pass through the filament, creating light. The electrons then continue flowing through the metal conductor to the positive terminal of the battery, completing the circuit.
Simple math rules state that a negative times a negative equals a positive!
Positive A simple rule to remember this is when multiplying two numbers with the same sign, the result is ALWAYS positive. When multiplying two numbers with different signs, the results is ALWAYS negative.
-12A negative times a positive is always a negative.A negative times a negative is always positive.
