Yes, this is basic electronics book in Bengali will help the students to learn Practical Electronics Education , uses of variety electronics parts, build circuit design using electronics parts and build any types of the circuit board. You can download the book from below link. It is completely free to download. A coulomb is one billion billion electrons.
Current Current is thus a measure of the rate of electrical flow. It can also be known as amperage or draw, and is measured with an ammeter. Current When two loads are connected parallel, as in the illustration on the left, each draws current independently of the other.
Current In the picture, bulb A draws 2 amps, while bulb B draws 1 amp. The total current flow in the circuit is 3 amps. Current Important: The total current draw in a parallel circuit equals the sum of the individual current draws. Current If the same two bulbs are connected in series instead of parallel, their combined resistance will be 18 ohms. Resistance Even conductors have some resistance; for example, a piece of 22 gauge copper wire 60 feet long has one ohm of resistance.
Larger diameter wires have less resistance. Heat generally causes resistance to increase in a conductor or connection. When resistors are in parallel, the total resistance equals the source voltage divided by the combined current draw. With a 12 volt supply, how much amperage would each of these resistors pull? So each 6 ohm resistor will pull 2 amps. Okay, if the total circuit pulls 4 amps, how many ohms of resistance would the total circuit have, based on a 12 volt supply?
With a 12 volt source, how much total resistance would this parallel circuit have? Voltage Drop The voltmeter at point A will measure the source voltage. If the voltage measurement is taken at point B, what will the voltage be? Voltage Drop Did you say zero volts?
The voltage drop is equal to 12 times zero, which comes to zero volts. Voltage Drop When two or more loads are in series: 1. The voltage drop of each load is equal to current draw times resistance.
The sum of all voltage drops equals the source voltage. Voltage Drop. That is, the closer you move your probe to the ground side of a circuit The voltage drop at the brightness control is 2 amps x 3 ohms, which equals 6 volts. Computing Parallel Resistances by Formula In this example,. Computing Parallel Resistances by Formula If there are only two resistances, multiply their values and divide by the sum of their values.
Computing Parallel Resistances by Formula. Power Sources The generator maintains the charge in the battery after the engine is started and supplies electrical current to all electrically powered equipment. Case Grounds are used where the component itself is securely attached to a well-grounded part of the vehicle. Grounds Remote Grounds are used where the component itself is not grounded Examples are reversible motors power windows, door locks and instrument panel warning indicator lamps.
Power is fed to the fuse Where is Through circuit Connector C? How do you find it? The male side of the connector is CM, while the femaile side is CF. Most wiring books have a location view like this. Find circuit What is the pin number?
What color is the wire? Write down both pieces of information. Locate the wire where it passes through a connector. Now we not only …we also know know where C what the connector is Find circuit number Write it down. With that in mind, we inspect all four pins, i. Now the circuit passes through a splice and two more connectors.
The splice could be a problem, but it is usually taped into the harness and can be difficult to locate. It should be examined last. This pinout legend is slightly different. Once again, we can find the connector on the vehicle, then locate the pin in that connector so that we can check the integrity of the circuit at the connector.
Find F7 on the grid and locate connector C Find it and write down the pin number. Once again, we can go to this connector, find the pin in question, and check the circuit. Our last inline connector is C Find E10 on the grid and locate connector C One more potential problem point is the ground, namely G Find E10 on the grid and locate connector G Distance is not indicated on a schematic….
Notice that the ground for the backup lamps is at the opposite end of the vehicle from the lamps…. Open navigation menu. Close suggestions Search Search. User Settings.
