If you don't know, you probably should just go ahead and call a plumber! Lol. Seriously though, hand tight with a nut driver is usually adequate

It is used to amplify the current. The common-emiiter amplifier is designed so that a small change in voltage (Vin) changes the small current through the base of the transistor; the transistor's current amplification combined with the properties of the circuit mean that small swings in Vin produce large changes in Vout. Various configurations of single transistor amplifier are possible, with some providing current gain, some voltage gain, and some both.

0.7 V

Even though it has only two types of charge carriers we will not call it as a diode but a transistor since it is a three terminal device.

Volts = amps x ohms so 30x15000 or 450000 volts. The power is 30x450000 watts so it's going to get mighty hot, very quickly.

It depends. XNOR is the inverse of XOR. If the N(ot) part is on the inputs, then they are equivalent. If the N(ot) part is on the output, then they are not.

The main reason for produce reverse current in a diode is "MINORITY CARRIERS". For reverse bias diode i.e negative terminal connected to p side and positive to n side the electrons in p side(minority charge carriers) attracted towards the positive polarity i.e towards positive terminal. Hence the current (reverse saturation) flows.Holes also contributed the current by attracting towards negative side.

Any complete circuit.

An electrical circuit.

For any power supply application you hav eto measure the supply specifications with the load specifications.

If the supply is AC the load should be designed to use AC and the same for DC to DC.

The voltages should match up.

The current that the load requires must be less than or equal to the current that can be provided by the supply.

Lastly the wires connecting the supply to the load must be sized to carry the current required by the load.

A: An application is a means to explain how where a particular IC or DEVICE or CIRCUIT can be used for. Example an op amp can be used for many applications amplify sum subtract generator multiplier and so forth. Each of these are application for a particular device.

A: Using a diode and a capacitor and replicating for the voltage that is desired. Be aware that the final voltage can be very hi for 120 v AC and be aware that the voltage is there but the power is limited due to repeating losses along the way.

Ohm's Law

Volts = Current x Resistance

Amps = V / R

110 / 20 = 5.5 Amps

A: As frequency increases all amplifier exhibits losses due to internal capacity or internal devices frequency limit. At the hi end of the frequency the amplifiers begins to loose gain gradually as a function of higher frequency that is what roll off is.

Clipping circuit is a wave-shaping circuit, and is used to either remove or clip a portion of the applied wave in order to control the shape of the output waveform. One of the most basic clipping circuit is the half-wave rectifier. A half-wave rectifier clips either the negative half cycle or the positive half cycle of an alternating waveform, and allows to pass only one half cycle. Such a circuit has great applications in radars, digital computers and other electronic systems for removing unwanted portions of the input signal voltages above or below a specified level. Another application is in radio-receivers for communication circuits where noise pulses that rise well above the signal amplitude are clipped down to the desired level. Clipping circuits are also referred to as voltage limiters, amplitude selectors, or slicers.

High voltage and low resistance would cause high amps. E = I R or I = E/R. PS E would be electromotive force measured in volts. R would be resistance measured in ohms. I would be current flow measured in amps.

Mega is 8 X 10^6 and Kilo is 8000 X 10^3.

For every 3 you go down in powers you divide by 1000, so 8 Mega ohms is 8,000,000 ohms. 8,000 Kilo ohms or 0.008 Giga ohms.

A: it must apply to AC since there is no phase in DC. Since AC is a complete circle 0-360 degrees the principle if to conduct current at a degree of the circle. And AC has both positive 0 to 180 and negative 180 to 360 polarity it is possible to control output power by conducting current only at certain angle of the circle . The phase angle is to differentiate the conducting current in which quadrant of the circle

It can be converted using a Shift register.

A Serial-In-Parallel-Out(SISO) shift register is used to convert temporal code to spatial code.

A Parallel-In-Serial-Out(PISO) shift register is used to convert spatial code to temporal code.

Brake test is used to determine the efficiency of comparatively small motors. The motor is loaded directly by means of a mechanical brake (load) or by means of an eddy current or a calibrated air fan.

Electronic devices works on low level dc voltage like 48volts and less than that. We cannot give direct line supply to electronic devices, for this transformer is used to convert ac voltage to required dc level...

Whereas in electric devices we can use direct line supply (110V/220V) ac. These devices can also be operates on dc volts but greater than 48volts

It is generally accepted to be approximately .7 volts.

It would be zero because there is a leakage.

0 is smallest primary voltage division
