what is the difference between capacitor and resistor?
2428
The main difference between Capacitor and Resistor is that the Capacitor is a electrical component used to store energy for a short period of time and Resistor is a passive electrical dipole which providing a constant ratio between tension and current.

The opposition offered to the flow of current in an AC circuit because of resistance, capacitance and inductance is known as Impedance. Resistance occurs in both AC and DC circuit, whereas Impedance takes place only in an AC circuit. ... Resistance is denoted by (R) whereas impedance by (Z).

The difference is that in the case of a capacitive load, the current reaches its maximum value before the voltage does. The current waveform leads the voltage waveform, but in an inductive load, the current waveform lags it.

What Is a Capacitor? Capacitors are small cylindrical objects that store energy. They either send a jolt to start a motor or send jolts to keep a motor running. They work with the compressor, the blower motor, and the outside fan in your air conditioner.

Transistor: A discrete semiconductor device. Op-amp: A functional module consisting of multiple transistors and resistors and capacitors. ... Difference: A transistor is a single device, while an op amp is a functional module composed of multiple components. (The op amp contains multiple transistors.)

A supercapacitor differs from the ordinary capacitor in that it has much higher capacity and energy density, while at the same time having a higher power density. ... The capacitor is a passive electrical element, which accumulates energy in the electric field between the two conducting electrodes.

A diode only allows current to pass through it in one direction. A capacitor, in the context you've described, acts as a low impedance path to GND for high frequency signals. So a diode protects current from going in an unintended direction whereas a capacitor resists voltage (across it's plates) changing quickly.

Difference between carbon composition resistor and wire wound resistor. Its power rating is from ¼ W to 2W. ... It has high tolerance and hence, accurate value of resistance cannot be obtained. It has low tolerance and hence, accurate value of resistance can be obtained.

The power dissipated in a resistor is given by P = V2/R which means power decreases if resistance increases. Yet this power is also given by P = I2R, which means power increases if resistance increases.

The current flowing through a resistor at a constant temperature is directly proportional to the potential difference across it. This is called Ohm's law. When resistors are connected in series, the total resistance of two or more resistors is the sum of their individual resistance.

Capacitor is a device that is used to store an electric charge. It is basically an arrangement of conductors. Condenser is an old term for a capacitor. Therefore, there is no difference between a capacitor and condenser in electronics.

Let us understand what is the difference between AC and DC resistance. The resistance of the conductor is inversely proportional to the cross section area through which the current flows. ... The AC resistance of the same conductor is always more than the DC resistance because of the skin effect and proximity effect.

A capacitor is able to discharge and charge faster than a battery because of this energy storage method also. ... However, in general batteries provide higher energy density for storage, while capacitors have more rapid charge and discharge capabilities (greater Power density).

When a capacitor is fully charged there is a potential difference, p.d. between its plates, and the larger the area of the plates and/or the smaller the distance between them (known as separation) the greater will be the charge that the capacitor can hold and the greater will be its Capacitance.

The potential energy in a capacitor is stored in an electric field, where a battery stores its potential energy in a chemical form. ... However, in general batteries provide higher energy density for storage, while capacitors have more rapid charge and discharge capabilities (greater Power density).
