A coulomb is a measure of electric charge and is equal to -6.24151 x 10^18 electrons.

As it is clear form your question that it will be LV winding.

Oil is used to cool the transformer. There is no telling what the transformer in question uses without knowing the specific part number and looking up the specification.

Use a properly rated potentiometer.

The main application for a core type transformer is to increase voltage from a standard 240v supply up to 415v instead of using a 3 phase supply.

the maximum rating is 60 hz . it is work in50hz

Transient emissions are" unwanted high voltage generated during ON and OFF the Electronic or Mechanical switches".this will cause some unwanted function in the system.

A: SURE capacitors in parallel will share the charge. But don't expect a .0001 mfd capacitor to charge a 1000 mfd capacitor. It just does not have the power stored to effectively charge the 1000 mfd. EXAMPLE 1litter of water cannot fill up a 5 litter container

A; Many years ago the industry established a standard of 5 volts as an operational power. This is no longer true. But the reason was is to provide bias for the inputs to establish a level of triggering and also provide noise immunity with hysteresis

The voltage across a battery in a parallel circuit is equal to the voltage across each bulb because Kirchoff's Voltage Law (KVL) states that the signed sum of the voltages going around a series circuit adds up to zero. Each section of the parallel circuit, i.e. the battery and one bulb, constitutes a series circuit. By KVL, the voltage across the battery must be equal and opposite to the voltage across the bulb.

Another way of thinking about this is to consider that the conductors joining the battery and bulbs effectively have zero ohms resistance. By Ohm's law, this means the voltage across the conductor is zero, which means the voltage across the bulb must be equal to the voltage across the battery and, of course, the same applies for all of the bulbs.

Parallel to each other.

Because its function is to measure the current, i.e. the amount of electrical flow in the circuit, and this require that the current flows through the ammeter A good ammeter has very low series resistance, so connecting it in series will not affect your circuit. Be careful when using an ammeter , because of its very low resistance , it can cause a short circuit if you use it by mistake to measure "voltage", so avoid connecting it in Parallel.

due to commutation the current in the coil reverses

P=ie

Yes, a diode inherently has polarity, as current is only allowed to flow one direction.

a: its function is to detect a change of light withing its perimeter

250 kVA generators come in different voltage settings and this information is needed before a wire size can be given

A sine wave centered at zero will have a positive peak that is the same magnitude as the negative peak. This can be offset so the negative peak magnitude does not match the positive peak magnitude. For example a 1volt peak - neutral sine wave could be DC offset by 1 volt so the positive peak is at 2 volts and the negative peak is at 0.

Step-Up Transformers increase the primary voltage to a higher voltage, of same frequency.

A: The essential difference is while it will behave like a normal diode at some at .6 forward voltage it has a negative impedance area before this point is reached it is not a very stable area to maintain and has the tendency to switch from one mode [low level] to the other .6v and very fast endeed.
