A capacitor is a device that resists a change in voltage, proportional to current and inversely proportional to capacitance.

dv/dt = i/c

An inductor is a device that resists a change in current, proportional to voltage and inversely proportional to inductance.

di/dt = v/l

In an AC circuit with capacitive loading, the current waveform will lead the voltage waveform; while with inductive loading, the current waveform will lag the voltage waveform.

What is the Difference between resistive and capacitive load?

when a resistive load is applied there is no phase angle difference between voltage and current. when a inductive load is applied there is phase difference between voltage and current. current lags voltage by an angle of 90 degrees for pure inductive load


In a purely resistive ac circuit the current and voltage?

Voltage and current will be in phase for a purely resistive load. As a load becomes more inductive or capacitive, the phase angle between voltage and current will increase.


What is the difference between transformer coupling and RC coupling?

RC COUPLING :- is the most Commonly used Coupling Between the two stages of a cascaded or multistage amplifier because it is cheaper in cost and Very compact circuit and provides excellent frequency response. TRANSFORMER COUPLING :- Impedence Coupling results in more efficient amplification because no signal power is wasted in Inductor L. Such Coupling has the drawback of being larger, Heavier and Costlier than the RC COUPLING. Impedence Coupling is rarely used beyond audio range . by : Muhammad zubair.... muet student of telecom.


Difference between inductance and inductive reactance?

The opposition to AC current flow in a circuit due to induction is called inductive reactance.The process of generating electrical current in a conductor by placing the conductor in a changing magnetic field is induction or just induction.


What is meant by resonance in LCR circuit?

a circuit in which inductance L,capacitance C and resistance R are connected in series and the circuit admits maximumum current corresponding to a given frequency of a.c.Another AnswerIn the case of a series circuit, resonance occurs when its inductive reactance is exactly equal to its capacitive reactance. As the vector sum of these two quantities will then be zero, the only opposition to current will be resistance and, so, maximum current will flow through the circuit when resonance occurs. ALL circuits can be made to resonate at what is called their 'resonant frequency' because, as frequency increases, the inductive reactance increases but capacitive reactance falls -so, at some point the two will equal each other, and resonance will occur.In my view resonance means - the condition that exists when the inductive reactance and the capacitive reactance are of equal magnitude, causing electrical energy to oscillate between the magnetic field of the inductor and the electric field of the capacitor.

What are the minimum amount of winding of coil for inductive coupling to take place between two metal coils?

Not even a single turn, just having two wires "near" each other will cause some inductive coupling between them. This is one of the causes of "crosstalk" that causes signal to appear in weakened form on wires they don't belong on (the other cause is capacitive coupling, which is also present between any two wires "near" each other).The real matter is how much coupling you want (or can tolerate, if you don't want coupling).

What is the difference between capacitive and inductive sensors?

Inductive sensors use a magnetic field to detect objects. Capacitive sensors use an electric field. In order to be sensed by an inductive sensor an object must be conductive. This limits suitable targets to metal objects (for the most part). In order to be sensed by a capacitive sensor the target doesn't need to be conductive. A capacitive sensor will react to an object acting as a dielectric material as well as a conductive object. This makes metal and non-metal objects suitable targets.


What is the difference between an inductive and a capacitive load?

Resistance load it means there is passive load to impede current flow. Inductive load means there is a coil as a load while still a passive it has its own characteristics which differs from a resistive load which is linear while inductive is not linear load


What is Pure Resistive?

A purely resistive load is one in which there is no capacitive or inductive reactance. Whe driven by an AC voltage source, such a load will have no shift in phase angle between voltage and current.


Does op-amps use internal capacitive coupling between stages?

No. An op-amp is a DC coupled device.


What are the differences between capacitive and inductive loads and how do they affect the performance of electrical systems?

Capacitive loads store and release electrical energy, while inductive loads resist changes in current flow. Capacitive loads can lead to power factor issues and voltage fluctuations, while inductive loads can cause voltage drops and power losses. Balancing these loads is important for efficient electrical system performance.

What is the difference between descriptive statistic and inductive?

The descriptive statistics deals with prediction. The inductive and the deductive statistics basically deals with presumption. The inductive statistics is used in making predictions.


What is the difference between a socket and a coupling?

A socket is a female fitting that connects to a pipe or tubing, while a coupling is a device that connects two pipes or tubes together. Couplings can be either rigid or flexible, while sockets are typically fixed and do not allow movement.
