Electronics Engineering

there is no element that can't conduct electricity, only elements that do it well and others that don't do it so well.

Rubber is a very poor conductor of electricity, while copper, silver and gold are very good conductors.

hey

Both will kill you easily ;)

But medium/high voltage, high current DC is generally considered 'more dangerous' as it tends to make people clamp onto the cable rather than being thrown away from it, so fault current is suffered for longer as a result.

Hope this helps.

ANSWER : NOT TRUE VOLTAGE DOES NOT KILL current however will even a 'D' cell can kill you [able to deliver 2 amps] Now which is more dangerous DC for sure it is continuous AC WILL PASS TROUGH ZERO AT TIMES ENOUGH MAYBE TO DISCONNECT

There is no such thing as a d.c. transformer; all transformers work on a.c.

So, what you are probably referring to is a power supply: the type of thing you would use, for example, to run a small radio or to charge a battery.

In that case, no, you cannot plug a a.c. appliance into a power supply that has a d.c. output.

Yes. Most flashlights have a series circuit involving a battery, a switch, and a bulb. More complex variants might have two bulbs in parallel, two or more bulbs on two switches, etc. but the basic principle is a series circuit - turn the switch on and the bulb illuminates.

serial adder:

1) Slower

2) It uses shift registers

3) IT requires one full adder circuit.

4) It is sequential circuit.

5) Time required for addition depends on number of bits.

Parallel adder:

1) Faster

2) It uses registers with parallel load capacity

3) No. of full adder circuit is equal to no. of bits in binary adder.

4)It is a combinational circuit

5)Time required does not depend on the number of bits

Electric device means a device which works by using electric power or current and it's working principle or working area is shown whoever sees it. Where as electronic device means it can work by consuming electric power or battery power, but we can not see the working principle , i.e , how it is working ,and just we see the result. Electronic devices are preprogrammed and it consists of chips (which are small pieces, encapsulation of programs.

All the volt drops across each component in the series circuit will add up to the emf of the battery or power supply. Note the voltage supplying the circuit and divide it by the sum of all the resistances in the circuit. This gives you the current which is the same through all components. Take a component's resistance and multiply by the current and you have the voltage drop across it.

the unit of measuring for displacement is cubic centimeter[cc].

The unit of measurement for displacement is the meters.

A potentiometer is a type of position sensor. They are used to measure displacement in any direction. Linear potentiometers linearly measure displacement and rotary potentiometers measure rotational displacement.

Also known as a Potmeter or Pot, it consists of a resistive element called the track and a sliding contact called the wiper internally where end terminals are attached to the resistive element.

They are used to accurately measure voltage and help achieve a variable voltage from a fixed-voltage source.

Common Examples of Potentiometers are:

• Measuring Position on a gaming joystick
• Controlling audio equipment using volume controls

If the gate-channel junction of a JFET was not reverse biased the JFET would just act as a forward biased diode across that junction and the gate would cease to have any control over the channel conductance.

For the same reason in a MOSFET the substrate-source/channel/drain junction must remain reverse biased. The MOSFET could not act as a MOSFET.

Simple diode is a two-terminal pn-junction with appropriate contacts for connecting the junction to external circuits.

Power diode is formed by alloying, diffusion, and epitaxial growth. The modern techniques in semiconductor fabrication processes permit the desired device characteristics.

The operation of power diodes is similar to that of signal diodes; but it has larger power-, voltage-, and current-handling capabilities than those of ordinary diodes. Switching speed of the power diodes is low compared to that of signal diodes.

From ESD Association ESD Handbook ESD TR20.20 section 5.3.2.1:

"When people are charged with static electricity, they can release stored energy to conductive objects such as doorknobs and electronic circuits. This transfer of energy is called an electrostatic discharge. Sometimes the electrostatic discharge causes visible sparks, but more often, it is both unseen and unfelt. Electrostatic discharges can damage ESD sensitive components used in modern electronics.

Static electricity is a natural phenomenon that occurs in all climates and at all levels of relative humidity year round. Most people cannot feel an electrostatic discharge unless the static voltage is greater than 2000 volts. However, some electronic circuitry can be damaged by ESD that is less than 2000 volts. The damage can be done without people having any sensation of the ESD event.

When a wrist strap is worn properly and connected to ground, the person wearing it will stay near ground potential."

A; Must define the transistor type and its mode of application if you expect an answer. It has the capabilities to conduct both way on either type dueing saturation mode. Hope that helps

Current transformer is a device used to measure the flow of current through a power system and the measured current is inputted to a protective relay system. It is used to detect system malfunction.

Current transducer is a device used to measure AC and DC current based on the halt-effect technology.

when we provide two input as 1 or true or high out put of q and q' become same

that violate the complement law.

A microprocessor is a multipurpose, programmable device that uploads digital data, processes it according to memory-stored instruction, and provides output results. They operate on numbers and symbols represented in binary code.

A; fluorescent lamps needs 500 v to start once started the voltage drops to ~90 v the starter perform the kicking to get to 500 volts without it it will not start so taking it out after it started that is when it is not longer needed

Apparent power is the vector sum of a load's true power and its reactive power. If you draw a 'power diagram', the phase angle will be the angle between the true power and the apparent power. If true power is fixed, then increasing the phase angle will result in a greater value of apparent power.

A: Voltages varies on a circuit because current varies caused by difference in resistance

The Junction Field Effect Transistor (JFET)exhibits characteristics which often make it more suited to a particular application than the bipolar transistor. Some of these applications are:

- High Input Impedance Amplifier

- Low-Noise Amplifier

- Differential Amplifier

- Constant Current Source

- Analogue Switch or Gate

- Voltage Controlled Resistor
