Some voltage must be present but the current causes the arcing.

ordinary light is the thing that helps you see

Break down voltages happens at low voltages (.6 for silicon & .3 for germanium), whereas knee voltages at higher voltages. That's why its cheaper.

To turn a diode on, you need to apply a forward voltage across it, ensuring that the positive terminal of the voltage source is connected to the anode and the negative terminal to the cathode. This forward voltage must exceed the diode's threshold, known as the forward voltage drop (typically around 0.7V for silicon diodes and 0.3V for germanium diodes). Once this voltage is applied, the diode allows current to flow through it, effectively turning it on.

One of the differences between electric and magnetic fields is that magnetic field lines always form closed loops.

That depends on the output impedance.

In electronic we use voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is more than ten times higher then the output impedance.

An input impedance is called also a load impedance or an external impedance.

An output impedance is called also a source impedance or an internal impedance.

The analog method of signal transmission uses radio waves to carry signals. Digital transmission involves the use of satellites to transmit signals.

The LM741 pins depends on the particular package selected. The most common arrangement is...

1.) Offset Null

2.) Inverting Input

3.) Non-Inverting Input

4.) Supply Voltage Minus

5.) Offset Null

6.) Output

7.) Supply Voltage Plus

8.) No Connection

This is true for both the 8 pin metal can and the 8 pin DIP. Typical connection is to connect a 10K potentiometer between the two offset nulls with the wiper connected to Supply Voltage Minus.

in the open circuit test, the high voltage winding is open circuited and the measurements are made on the low winding side i.e, the open circuit test is performed on the L.V side. This is because if the measurements are made on HV side then voltage applied must be large and the current would be unsuitably small, for which the high voltage sources may not be readily available and at the same time the instrument ranges required should be very high, Also the result obtained may not be accurate.

NOTE: iron loss will be same, if measured from either of the winding.

in short circuit test. the low voltage winding is short circuited and the measurements are made on the high voltage winding side i,e,. the sort circuit test is performed on H.V side. This is because if the test is performed on the L.V side, the current will be suitably large for which the instruments used should be of very high ranges. moreover instruments of such high ranges and the auto-transformer capable of handling such high currents may not be readily available.

True

Six, Voltage is the same in a parallel circuit but current divides to total the sum of each branch. See Kirchoffs current law.

A: 1/7

R = E / I = 12 / (240 x 10-6) = 50,000 ohms = 50 KΩ

Six amperes. Use Ohm's law: the current is the voltage divided by the resistance

when the p-n junction is heavily doped p-n junction diode has very sharp breakdown voltage.

The occupations I think are relevant to creativity are the following-Actor, Vocalist, Poet, Fashion Designer, Entrepreneurial Independant, Sales Person, Interior Designer, Artist(Painter, Sculptor, etc), Jeweller, Nail Technician, Hair Dresser, Beautician, Toy Designer. I'll probably be back later with some more.

I = 2A R = 1000Ω Power Dissipated P = I2R = (2A)2(1000Ω) = 4000W Voltage across resistor V = IR = (2A)(1000Ω) = 2000V

No there not same

diodes

The difference is in the name. "Mono" means one, so a monostable circuit is a circuit that is only stable in one state. An astable "A" means without... is a circuit that is not stable in any state.

hope this helped!

how to disarm microchip implant?

The term normaly closed means that in its normal state the relay or contact is closed. So when energized it will open and break the circuit.

It would be the sum of the two resistances, as they are connected in series.
