Car Electronics and Lights

Need the voltage or current of the circuit. And the type of lamp (bulb)--is it incandescent, fluorescent, LED, discharge?

Also need to know the temperature--the resistance of a tungsten filament changes by a very large amount from ambient temperature to hot/operating temperature.

A rectifier turns the Alternating Current (AC) produced by the Alternator into Direct Current (DC) that your car uses.

The unit of measure of electrical pressure is the VOLTS.

The term converter usually refers to a DC to DC process where a higher or lower voltage is required. Even when a lower DC voltage is needed, it is sometimes more efficient to use a chopper style process rather than a voltage regulator. Converters are often used to condition dirty or highly variable sources like automotive, aircraft, and marine 12VDC systems into a very clean source of power for sensitive electronics. Many converters have very wide input voltage requirements that allow one design for a wide range of power 8-36 volts or more is not unusal. So you can operate even on almost dead batteries, or on a 24-36 V system without modification.

Inverter is a term that implies making AC from DC as in 12VDC input, 120VAC output.

This Is the correct answer:

DC (batteries) 12v to AC (house) 120v Inverter

AC (house) 120v to DC (batteries) 12v Converter

A Diode is a device which allows current to flow only in one direction (see forward bias).

Since a rectifier needs to convert Alternating current(bi-directional) into Direct current(uni-directional), solid-state diodes are usually used as rectifiers.

the High voltage rated diodes are power diodes while of low rating or normal voltage rating are considered to as ordinary / normal diode

Diodes perform a different function as switches. switches allow you to control wether or ot electricity is flowing. diodes only allow power to flow in one direction. A light emitting diode may be used as an indicator for wether or not power is flowing through a circuit.

The first commercially-successful electric motors were made around 1873 by Zenobe Gramme, a Belgian engineer. His electric generators (dynamos) were based on machines invented by Italian physicist Antonio Pacinotti in 1860.

A ganged potentiometer is two or more piggy-backed together that share a common shaft. Turn the shaft and you turn all the pots at the same time. Commonly used to adjust the volume or tone for both channels of a stereo amplifier at the same time. An ordinary pot has just one to a shaft!

A one diode rectifier is called a half wave rectifier and only allows current flow for the positive portion of the sine wave. A two diode rectifier, or full wave rectifier allows positive current flow during the positive portion of the wave as well as positive current flow during the negative portion of the sine wave. This results in a much cleaner DC power signal. The addition of a capacitor in the output circuit will clean up the signal very nicely.

Almost 17% of Americans own a GPS device, whether in their car or on their phone or other wise. An approximate number would be around 3,065,849 people, and the number continues to climb. (Maty 2013)

It is a semiconductor device with two terminals, typically allowing the flow of current in one direction only. It may also be termed as the electronic component with two electrodes known as the anode and the cathode. Most diodes are made with semiconductor materials such as silicon, germanium, or selenium. The diode acts as a valve in the electronic and electrical circuit.

Electricity is a huge subject, so the topics for any seminar will have to be based on whatever aspects of electricity are to be discussed.

Lots of things - your car has a engine that is used as a generator (your alternator). Cell phones that vibrate have a small electric motor with an uneven weight on the rotor which causes vibration as it spins. Fans (heater, attic, computer, etc.), many different toys - remote control cars, some airplanes, etc. Electric golf carts and cars. The list goes on and on.

yes,infact every diodes have certain limitations.The maximum value of current that can pass through it will normally be encrypted on it usually at the time of manufacture.

250 watts approximately

I assume you have a constant voltage supply. According to P=V^2/R => P*R=V^2, you have a 44.7 volt supply. If you change Resistance to 8 ohms, P=44.7^2/8 => P=250 watts.

It is under the steering column on the left side behind the plate that covers the bottom half under the steering column, two screws on the bottom of the plate will remove the plate, then yoiu have to remove the adjuster for the right side mirror

Actually, a transistor is a device made from semiconductor material, and they're used to amplify and switch electronic signals as well as electrical power. Before transistors were invented, product engineers had to use vacuum tubes and electromechanical switches in order to complete electric circuits.

Reversing polarity is not possible with an ac motor. Some do have wiring that will allow you to change rotation. The type and model of the motor can tell you if it is reversible.

Connect positive to negative, leaving the end positive and negative connections free to power circuits or devices. Connecting batteries in series adds the voltage of the batteries. For instance, connecting three 12v car batteries in series will create a total of 36v, enough for welding.

Low efficiency

If you have 14 watts, you have 14 watts of power. We measure electromotive force (EMF), which is commonly called voltage, in volts. EMF (voltage) is the force that will drive electron current flow, which is measured in amps. Simply put, power is current times voltage, or, said another way, watts is amps times volts. If you have 14 watts, you could have 14 amps at 1 volt, 7 amps at 2 volts, 2 amps at 7 volts, or any other combination of current and voltage with a product of 14. You may have picked up that because watts is amps times volts, we can say that a watt is a volt-amp. Extending that thinking, 14 watts is 14 volt-amps. There is no way to write 14 watts in volts, at least not without having a bit more information.

Yes, with a retroreflector. One form of a retroreflector is 3 mirrors all mutually perpendicular like the corner of a cube.
