Electric charge can be positive or negative both on large scales and fundamentally (eg the protons in atomic nuclei have a charge of +1 and the electrons that orbit those nuclei have a charge of -1 [units are arbitrary, if you want derived SI then these charges are +- 1.6*10^-19 C]).
You can also think of magnetic north and south poles as being 'positive' and 'negative' although this isn't strictly true.
Mathematically of course there are positive and negative numbers where the number -x is defined by the fact that x+(-x)=0.

Why do bulbs have two terminals?
One Terminal Is for Positive And Another Is Negative Wier . Bulb Can't Glow Until Both The Terminals Are Connected
How is static electricity is used in paint sprayers?
The paint is charged with an either a positive or negative charge, and the car part being painted with the opposite charge, the two charges attract and the paint sticks to the car part.This process ensures a uniform layer of paint, since when there is enough negative paint in the car the extra will be repelled by the paint already in the car.It also ensures that the paint won't fall off, since the electrical attraction between the paint and the car is stronger than if it was just sprayed.
What happens when you put the positive cable on the negative battery post?
Nothing unless you connect the negative cable to the positive post. When you do that you will destroy the battery and it may possible explode. You may also damage the electronics in the vehicle.
How do you tell the difference in the negative and positive on a coil?
Normally the terminals are marked on the coil ( if it's a bosch coil the one marked 15 is the primary winding positive terminal ). The large center one is the secondary positive ( the one that leads to your distributor ) and the two on the sides of it are the positive primary and the ground. If you don't know wich one is wich disconect the battery then disconnect the two smaller wires and remember wich one goes where. Use an ohm meter to test the resistance between a good ground on the body or engine block on each wire. The one that has no or very low resistance is the ground wire. If you are holding a coil in your hand and it isn't marked use the ohm meter to check the resistance between the secondary positive and the other two terminals. There should be infinite resistance ( open circuit ) to the positive of the secondary and 6Kohms or there abouts to the common ground terminal.
What causes battery to spark and jumpers to melt?
The current passed through them was too high. Possibly they are cheap cables, (many of them on the market today.) - Cables should be at least 10 gauge wire. Mine are 6. The thicker wire, the better quality your cables are. Anything thinner than 12 gauge is dangerous,.
When a positive and a negative are being multipied does it come out positive?
no, negative....if you multiply two negatives it comes out positive
What come in these two flavors positive and negative?
Lots of things. Some of these are: Electrical charge, Ions, Attitudes, Feedback,
What are two types of electric charge?
The two types of electric charge are positive and negative. Positive charges repel each other, as do negative charges, while opposite charges attract each other.
What is the sign of the quotient of two positive integers?
The quotient of two positive integers will be positive. A positive divided by a positive is positive. A positive divided by a negative is negative. A negative divided by a positive is negative. A negative divided by a negative is positive.
Is a negative divided by a positive zero?
There is no such thing as a positive or a negative zero. A negative divided by a positive is a negative, and a positive divided by a negative is a negative. If you have a negative and a positive, the answer will be a negative. But if you have two negatives or two positives as the dividend and divisor, the answer will be a positive. In other words, dividing two positives or two negatives will always give you a positive. But dividing a positive and a negative will always give you a negative.
What is the fundamental property of matter that comes in two types called positive and negative?
charge
What are the rules for multiplying integers?
Positive x Positive =Positive Positive x Negative= Negative Negative x Positive= Negative Negative x Negative =Positive
What will two negative parents have positive or negative baby?
a negative times a negative is a positive so the answer is positive
Is the product of two opposite numbers positive?
positive x positive = positive negative x negative = positive negative x positive = negative
Are the product of two opposite numbers positive?
No. The product of two opposite numbers is always negative. Negative x positive = negative and Positive x negative = negative
What are the two kinds of integer?
Two possible categories: positive and negative
What is tha sum of two positive numbersTwo negative?
positive plus positive equals positive negative plus negative equals negative
