What is the definition of capactive reactance?

reactance due to the capacitance of a capacitor or circuit,equal to the inverse of the product of the capacitance and the angular frequency.


What is the difference between capactive voltage transformer and potential transformer?

A capacitive voltage transformer (CVT) uses a (usually two) stacks of capacitors to reduce the votlage to a smaller internal potential transformer (PT). This makes them less expensive than an equivalent PT, but there can be a loss of accuracy.


Why is circuit current reduced when a capacitors added to the circuit?

In the case of an a.c. circuit, capacitors oppose current because of their capactive reactance, expressed in ohms. Capacitive reactance is inversely-proportional to the capacitance of the capactor and to the frequency of the supply. So, adding a capacitor is series with an existing load will reduce the load current. On the other hand, adding a capacitor in parallel with an existing load will decrease the load current.


What is the reactance of a rheostat?

In theory, a rheostat has only resistance. It lacks any capactive or inductive properties, and, therefore, has no reactance. In practice, a rheostat, which is like a potentiometer without a "third" terminal. One of the ends (terminals) of a potentiometer, if it is removed entirelym will leave a two-terminal device called a rheostat, or variable resistor. In practice, all similar devices have some distributed capacitance and inductance associated with them. The construction of the device as well as the materials out of which it is made (as well as the operating frequency) will determine how much reactance the device has.


What is the phase difference of RC circuits?

If you understand complex numbers then you will see that the imaginary value jXC which depends upon the value of C,capacitance, determines the value of the phase displacement angle.Answer">AnswerYou don't need to understand complex numbers to understand this topic. The term you are looking for is 'phase angle', not 'phase difference'. This is defined as the angle by which the load current leads or lags the supply voltage. For a resistive-capactive circuit, the load current leads the supply voltage and, so, the phase angle is leading. The actual angle depends on the values of R and XC (capacitive reactance). Incidentally, the 'displacement angle' is something different again!
