The ppm for a biometric system typically ranges from 0.5 to 2.0.

• PPM stands for parts per million, which is a measurement of the concentration of a substance in a solution.

• For biometric systems, the ppm refers to the error rate or false acceptance rate of the system.

• A lower ppm indicates a more accurate biometric system.

• Typically, a biometric system with a ppm of 0.5 to 2.0 is considered reliable.

An alternator is a device that converts mechanical energy into electrical energy.

• An alternator consists of a rotor, stator, and diode rectifier.

• When the rotor spins, it creates a rotating magnetic field.

• The rotating magnetic field induces an alternating current (AC) in the stator windings.

• The AC is then converted into direct current (DC) by the diode rectifier.

• The DC output is used to charge the vehicle's battery and power electrical systems.

• Alternators are commonly used in v...read more
