Overall cars are probably neutral - they allow for rapid travel so they help interconnect the national population and provide a great deal of freedom of movement to individuals. However, they can be expensive to purchase and maintain, they are involved in thousands of injuries and deaths every year and they contribute to greenhouse gas emissions.
How much weight you put on each of the above will determine how you personally rate cars.
NO! positive is red and black is negative negative is grounded to the frame of the car, and positive goes to the electrical components.
If you want to jump start your car, connecting negative to negative and positive to positive is the only way to do it. Connecting negative to positive will result in extensive damages to the electric systems of both cars.
The center is the positive.
On the car battery, the positive wire is red and the negative wire is black. If the body of the car is metal or conducts electricity, then the body of the car serves as the negative wire. The metal in the engine serves as the negative wire.
You could put them in parallel--wire positive to positive, negative to negative, then connect the positive and negative wires to the car. This would give you twice the current capacity, and you'd be okay because the car's only going to take as much power as it needs. If you wired them in series--positive on the first battery to the car, negative on the first battery to positive on the second, negative on the second battery to the car--you'd double the voltage and burn the car out.
Positive is either red or has a "+" symbol.
The current flow is from positive to negative whereas electron flow is from negative to positive.
Negative ground
Normally Positive (+) is RED and Negative (-) is Black.
You will damage the electrical system of the car
negative work
The "+" sign is used to mark the positive post.
