Electronics Engineering

Electronics Engineering is a branch of engineering that deals with practical applications of electronic components, devices, systems, or equipment. Electronics are devices that operate on low voltage sources, as in electron tubes, transistors, integrated circuits, and printed circuit boards and use electricity as part of its driving force.

What is the flow of charges between two objects called?

A flow of charge is called a current. It is measured in coulombs per second per amperes.

Why does less current run through a circuit when there are more loads?

This happens only in pure series circuits, due to increased resistance.

What is Course Load?

The number of courses, total credit hours, for one student for an individual semester.

How do i know what wires to connect together on an ac transformer?

All transformers are AC. Your question also does not contain enough information. If it is a multi-tap transformer, the wiring will be unique to the manufacturer but is very often indicated on a label or printed onto the former or case of the transformer. If it isn't a muti-tap transformer, no wires should be connected together, or you have worded the question very badly.

How many classes of diffraction?

fresnel diffraction and fraunhoffer diffractions

What is the LSB input of a 7 segment decoder?

It all depends. You need 3 bits to get 8 potential States.

000

001

010

011

100

101

110

111

From top to bottom this counts from 0 to 7 in binary. In this example, the LSB for the sequence above would be 0, 1, 0, 1, 0, 1, 0 and 1. You really have to look at the overall decoding scheme. If you had a device with 7 inputs then you could assign each input to a specific segment. Depends on what you have to amswer your question precisely.

In a series circuit each device that is added to circuit decreases the?

Ohm's Law answers your question. Voltage = Current x Resistance. In a series circuit you are in effect adding resistance. If the Voltage remains constant then the answer is obvious looking at the equation above.

How much power is produced by 500mA of current through 4.7kΩ resistor?

1,175 watts. Which isn't very feasible

As it infers a voltage of 2350 Volts across the resistor.

Pls recheck you numbers and resubmit

Why is collector current slightly less than emitter?

The percentage of doping in emitter is higher than collector region.hence large current is flow to emitter than collector.

What does circuit mean in a clock?

In the context of a clock, a "circuit" refers to the electronic pathway that enables the clock's components to function together. This includes the connections between the power source, timing mechanism, and display elements. The circuit ensures that signals are transmitted correctly, allowing the clock to keep accurate time and display it properly. Essentially, it forms the backbone of the clock's operation.

What is the history of the electric circuit?

the history of the electric circuit is that the person who made it his name is jack kilby but the history is that the electric circuit was one of the easiest way was to make the electric circuit when the electricity went out.

THE END

What pressure or force that causes current flow through a conductor is caleed?

The pressure or force causing current to flow through a conductor is called voltage.

What is the difference between AND gate and NAND gate?

An AND gate gives a 1 or True output only and only if all the inputs are True or 1. If even a single output is False or 0, it will not give any output meaning thereby that the output will be False or 0.

A NAND gate is quite the reverse of an AND gate and gives an output of 1 or True only if both the inputs are not True or 1. This means that even when both inputs are 0 or False, it still gives a True or 1 output.

A circuit has two resistors of equal value in series The voltage and current in the circuit are 20 volts and 2 amps respectively What is the value of EACH resistor?

Ohms law states

Voltage = Current X Resistance, or as commonly represented, E=IR.

In this case plugging in the values (using basic algebra)

20 = 2R

or

10 = R

or as commonly stated

R=10.

So that lets us know the TOTAL resistance of the circuit.

Now, knowing that series resistance is "added", we can calculate the individual circuit resistance.

In a series circuit total resistance can be represented by 'R', and the individual resistance of each resistor can be represented by "R1", "R2", R3", and so forth. In a series circuit resistances can be calculated using the formula: R=R1+R2+R3...

Since we only have the two resistors the formula would be:

R=R1+R2

Knowing that the resistors are equal in value we can assume:

R=R1+R1

OR

R=2(R1)

OR

2(R1) = R

OR

R1 = 1/2R

Given that R is 10 (from above)

R1=1/2 * 10

or

R1 = 5

Each resistor equals 5 ohms

Can you calibrate thermocouple with ice?

Yes, you can calibrate a thermocouple using ice by creating a stable reference point. This is typically done by preparing a mixture of crushed ice and water, ensuring the temperature remains at 0°C (32°F) at sea level. By immersing the thermocouple's sensing tip in the ice-water mixture, you can check its output against the known reference temperature and make necessary adjustments or corrections. This method is effective for verifying the accuracy of the thermocouple at low temperatures.

What is NAND gate in semiconductor devices?

A NAND gate is digital logic device which will have 2 or more inputs which can be logic 1 or logic 0 (on or off, high or low) with all the inputs at logic 0 the output will be at logic 1, the only time the output will switch to a logic 0 is when ALL the inputs are at logic 1.

here is a simple "truth table" To show the basic operation

Input1 Input2 Output

Off--------Off------- On

Off--------On------- On

On--------Off------- On

On------- On------- Off

NAND stand for not AND therefore a false will be present on the output only when both input are true

ANSWER: NAND stands for NOT AND it simply negate the function. The only time that the output can be false if all inputs are true. In logic functions there is no ON-OFF it is either true or false "1" or "0"

In a circuit if the switch is closed how many volts go across the switch?

For an ideal switch, there will be no voltage drop across it. In reality, there will be a very small voltage drop, and this will be dependent on how well made the switch is, and what it is made out of.
