As previously discussed, the electrical resistance of metallic conductors increases as temperature rises. Non-metallic semiconductors on the other hand
generally behave just the opposite. Their electrical resistance decreases as the temperature increases.
NTC Sensors are used in fuel injection systems and climate control systems, wherever accurate temperature input information is required.
Electrical Circuits
CIRCUITS
Batteries and AC generators (alternators) apply electrical pressure and cause an electric current to move through a circuit from the positive side to the
negative side. But there must be a complete circuit or electrical path made up of wires or other conductors or a current will not flow. If a wire is broken
or disconnected, current stops. Circuits are not all alike and electricity does not behave exactly the same in different types of circuits. Therefore, it is
important for you to understand the basic kinds of circuits found in an automobile and the way the volts, amps, and ohms behave in these circuits.
An electrical circuit is a continuous loop made of conductors (wire), a power supply, and a component, such as a lamp, which is the load. The two basic
