The current in a circuit is a measure of passing electrical charge per second. Each electron carries a fix amount of charge. Therefore the number of charge moving depends on the speed of the charge, in this case electrons. In conductors like copper, there are just so many free electrons that they move in bulk slower than snail.

The the Cathode ray tube, the speed is at a fraction of speed of light, not many electrons are flying.

For actual number, look up speed of electron in copper at room temperature, and multiple the electrical charge constant to get at the current. This must be a standard class tutorial.

A split phase induction motor has two sets of coils and a centrifugal start switch. The start winding is in series with the start switch. The start winding provides a rotating magnetic field in one direction enabling the motor to start. The motor can be reversed by reversing the connections of either the start winding or the run winding but not both.

A low voltage capacitor is an electrical component designed to store and release electrical energy at low voltage levels, typically under 50 volts. These capacitors are commonly used in various applications, including power supplies, signal processing, and filtering in electronic circuits. They come in various types, such as ceramic, electrolytic, and film capacitors, each suited for specific purposes based on their characteristics and performance. Low voltage capacitors help stabilize voltage levels and improve energy efficiency in electronic devices.

I have an AT-271 Antenna which seems to hav e been unused and it has stenciled on it

For example: if the primery winding on the transformer were 250 turns and the 1250 turns on the secondary, what is the turn ratio? Well what you do is you take 1250 divide that by 250 will give you 5. So the answer would be 1:5 since 1 will be on the top of the 250 and the 5 would be on the top of the 1250. IN ALL STEP UP TRANSFORMERS HAVING A TURNS RATIO MORE THAN ONE...BECAUSE IT STEPS UP VOLTAGE.

First, check the nameplate on the motor. The FLA or full load amperage is the required start up current and is typically 125-150 % higher than the running load amperage (RLA). So a current draw of 39.5 while starting would be normal for a motor drawing 25 A in run mode.

You don't need any calculations. If the stated RLA is close to 25 A and you're drawing 25 A then the motor is fine. As long as you're supplying the correct full voltage required by the motor, it will operate at "full capacity". There are numerous formulas for motors. I would need to know the motor's horsepower, voltage, whether it's single or three phase and its stated efficiency (EFF on the nameplate), the FLA and RLA to tell you if the motor is running properly or if it's going bad.

Generally accuracy at low current values isn't important for protective functions. The burden is taken into account when looking at the saturation curve and available short circuit current to insure the CT doesn't saturate during fault conditions.

Read less than 1 ohm

These are the most dangerous faults because you will be dealing with very high fault levels. Phase to phase will have very little to limit the impedance of the fault current. And phase to ground faults can be high since most systems are solidly grounded. Arching faults and faults through an impedance will be lower and cause less electrical and mechanical stress on the system.

Cross field revolving theory is the theory which discuss the cause of single phase induction motor not to be self starting. According to it, two different forces of same magnetude acts on the rotor in just opposite direction.Which makes the rotor standstill.

very good

There is no relation between the value of a resistance and whatever name you choose to call such a thing. But traditionally, for obvious reasons, use of the small letter r means there is an expectation that it will be smaller than one called R.

resonance is the behavior of resonant frequency while resonant frequency is the cause of it. There are basically two types of resonance; Electrical and Magnetic. Resonant frequency is that particular frequency for a system for which the system performs its best. while the system at that particular situation can be called the system at resonance

That depends on the circuit. For a pure resistive circuit (no inductance and capacitance), the frequency will have no effect on the current.

It can be done with 90% efficiency.

don't worry

A meter bridge operates on the principle of a balanced Wheatstone bridge, which requires precise measurements of voltage and current across its segments. When measuring large resistances, the current flowing through the circuit decreases significantly, leading to a high voltage drop across the unknown resistance and making it challenging to achieve a balance. Additionally, the sensitivity of the meter bridge diminishes with higher resistance values, resulting in reduced accuracy and potential measurement errors. Thus, meter bridges are typically limited to measuring moderate resistances.
