Electronics Engineering

V = IR

= 8x10-3 (8 mA) * 10x103 (10k)

= 80v

V=I*R

Where:

V is voltage

I is the current in ampers

R is resistance in ohms.

So, if the current is 15 A and the resistance is 5 ohms, then the voltage must be 15 A *5 ohms = 75 V.

A: THE EMITTER resistor sole function is to provide stability if it is by passed by a capacitor then this resistance will change due to frequency since as frequency increases the impedance decreases. The total gain will change accordingly

Get a charging kit from an auto parts store. This should include a gauge (or gauges) and freon. Your '98 uses the new type of freon so you don't have to worry about conversion. Follow the instructions on the kit. You will need to locate the charging ports (high and low side) and put the proper amount of freon in the correct port until you reach the right pressure. You'll need the engine running and the A/C on high while you do this. Don't overcharge - you need to use a gauge.

Communications - The amplitude of a carrier wave is modulated by a data signal and transmitted, for example by radio wave. At the receiving end it is possible to demodulate the signal if the orignal carrier wave is known and retrieve the data signal

By Ohm's Law, current is voltage divided by resistance, so a voltage of 6 volts across a resistance of 24 ohms will develop a current of 0.25 amperes.

paper clips are usually made out of steel wire. Some are made out of plastic.

A: If you means for a car it would be 13,68 volts minimum. But what is really important is the amperes out of it that is what is needed to charge a battery and that can be as high as 100 200 amperes out of the generator. Once the car has started the battery is no longer necessary to run it the generator and the regulator will just do fine.

p-type or n-type semiconductor alone is of very limited use in chips -- you can only make a thin-film resistor or parallel-plate capacitor with it. You also need the opposite type, the n-type semiconductor, to make junction diodes and MOS or bipolar transistors, which are essential components in an integrated circuit.

================================

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.

yes

the current can flow through a short circuit but there is no voltage because of the zero resistance

hence current through the circuit will be infinite

The above is of course a strictly theorethical truth. In the real world, several things limit current. The power source has a finite capacity, sometimes expressed as internal resistance, sometimes in max current, etc. All the wires, connections, and switches also have resistance. At high levels of current like this, even a small resistance will introduce a significant voltage drop. Use Ohms law, and you'll quickly see that with small amounts of resistance, infinite current isn't a real world situation. Likewise there will always be a certain small voltage, otherwise, there could be no current..

it converts it to a diode. sometimes this is done for matching the characteristics of diodes and transistors in the circuit. standard diodes might not have similar enough curves to the transistors for the circuit to operate correctly.

Power (P) = Voltage (V) x Amperage (I)

Written as

P=VxI

or to find Voltage

V=P/I

Voltage is measured in Volts (V)

Amperage is measured in Amperes (Amps or A)

Power is measured in Watts (W)

In simple terms a short circuit is when negative & positive

come together I:E a cable (positive)that is frayed touches the ground (negative).

A short circuit is also known as a dead short.

An example of an overload might be.

If the wiring in your car headlights was rated at 20 Amps & you

wired driving lights into that circuit, the Amperage draw would go up to 40 Amps

Causing the fuse to blow, or if the circuit was unfused, the wiring to burn out.

Transistor failure can occur due to a variety of reason. The following are some of them.

Age

Aging of transistor due to temperature variations inside the components due to carrying current can cause failure. The electrical properties of the materials inside can drift due to age.

External Causes

External causes such as spikes in the power supply, heat, mechanical damage can also result in transistor failures. Hence, all transistors should be adequately protected against overvoltage.

Poor Circuit design.

Improperly chosen components and wrong circuit design can also result in transistor failure. Hence, all components in the circuit should be properly rated with sufficient allowance for overloading and temperature rise. The failure of one component can lead to cascade failures of other components.

Overheating

Overheating is the most common cause of transistor failure. Hence, it is important that transistors be provided with cooling mechanism. Devices which contain temperature-sensitive electronic components should be kept in air conditioned environments.

Electrostatic Discharge

Electrostatic discharge can also damage transistors. Hence proper precautions against Electrostatic Discharge Should be taken.

It depends on:

1. technology, whether it's a JFET, enhancement-mode IGFET/MOSFET or depletion-mode IGFET/MOSFET, and

2. polarity, whether it's an N type or P type.

More info needed for this one.

Vout means goat in Germany

Linear mode

By knowing what TYPE of pipng such as cast iron/ Steel / plastic /WALL THICKNESS / copper / TYPE of copper as each type K/ / M /DWV / ACR all have a different wall thickness thus different restrictions

R = 1/[1/2 + 1/4 + 1/6 + 1/10]

Add up the reciprocals of the resistances, and take the reciprocal of the answer.

Umm, they really dont drive?? people drive them, you need to learn to drive then you can drive the car... it's quite obvious really......
