The op amp can only output so high a voltage; this is limited by the positive and negative voltages applied to the op amp. Your input signal is too strong, or your amplifier is set up to have too much gain.

Yes. Almost every electronic device consumes energy, however small. However the power draw of a voltage regulator is extremely tiny, typically less than 1mA. As such, they usually save more power than they consume.

You can do simple resistance tests on the various diode junctions. Measure each of the pairs of diode junctions. Collector-emitter, collector-base, base-emitter. Read the resistance of one junction and then read the same junction with the polarity probes switched. One side should read very high resistance, over 1 megohms. And the other should read a moderate resistance, a few hundred thousand ohms. If this is the case for all three junctions, the transistor should be a good working one.

We use double rating transformer, in this we have two type of cooling . ONAN & ONAF, According to cooling we have two rating.

Because you touch yourself at night.

i had mine running in my house i had it running off a battery charger at one point worked great just had to get an antenna out to the outside of the house but if you are just buying it and not going to modify anything with it then no you cant just plug it into a house hope this helps any question feel free to ask

A 'core type' transformer core is one in which the primary windings and secondary windings are placed around each of the limbs, as opposed to a 'shell type' core, in which the two windings are placed across the centre core. A core-type core is a magnetic circuit equivalent to an electric series circuit, whereas a shell-type core is equivalent to an electric parallel circuit.

Resistor placed in the emitter lead of a transistor circuit to minimize the effects of temperature on the emitter-base junction resistance.

If they are the same voltage a logic gate could combine them in various ways.

A ring modulator fed from two square waves would make interesting sounds.

An op-amp would combine the waves.

A single fet would combine them. One signal flowing from source to drain modulated by the second frequency applied to the gate.

To avoid accumulation of moisture.

yes... this is possible if a diode i connected in reverse bias with a battery and a resistor for example. A diode in reverse bias means its anode will be connected to positive terminal of the battery and its cathode to the negative terminal of the battery. In such a case, minimal current flows through the circuit which can be neglected.

Because the components are much more detailed and difficult to draw in real life

to investigate change in resistance as temperature is varied

Regulating the medium of welding according to the needs

Single phase requires 2 wires - a hot, and a return (both wires of the same size. Three phase requires three (same size), and if it is grounded will require a forth (doesn't normally carry current so it can be small). Two phase requires three wires (two phase conductors of one size, and a return that can handle double the current of the phase conductors), or four wires (same size for all, effectively two separate single phase supplies).

It isn't economical is the bottom line. It costs ~the same (in wire) for two phase as three, and you get 50% more power delivering capability with three phase.

To answer this question a voltage is needed.

Yes, the 2 Hz will not make any difference at all. As the frequency gets lower the motor will run slower but you will never see 2 Hz in speed reduction.

A: Checking continuity is the same as checking resistance, therefore yes someone can determine the resistance at that particular current level

Yes, but only if the magnet or the wire are kept moving.
