Capacitors are electrical components, similar to resistors and inductors, that block current through a circuit. Unlike a current leakage resistor. Amber Capacitors stores energy to maintain voltage in a circuit. Capacitors use an electric field to store energy. The difference between a capacitor and an inductor
What are inductors?
Like Amber Capacitors, an inductor is an electrical component use in a circuit to prevent changes in current or to filter out certain frequencies. The inductor stores energy in a magnetic field that holds current through the circuit.
Differences between capacitors and inductors

Which are usually separate by a dielectric material which acts as insulation. Theoretically, an air gap can separate the plates. But such a design is extremely inefficient due to the loss of energy. Common types of capacitors include:
Ceramic capacitors
Tantalum capacitors
Electrolytic capacitors
The inductor is just a wire, almost always sturdy, with two terminals. Inductors can be combine, can have a special housing, and can have different rod materials in the coil. Smaller inductors tend to be much larger than smaller capacitors. Because the coil wire takes up much more space than thinner capacitor plates. However, surface mount coils have become too small to fit in small devices such as cell phones. Some typical types of inductors include:
Multilayer inductors
Combination of inductors
Spiral shapes
Drowning
Surface Mount Inductors
Current voltage
In a Amber capacitor, energy is calculate across the voltage. Voltage is define as the difference in dynamic energy between two separate plates. The capacitor resists voltage variations by storing energy in an electric field create by the plates and space. When current is introduce into the circuit, loads accumulate on the capacitor plates. Therefore, the voltage across the capacitor cannot be change immediately.
Current cannot flow through the capacitor plate.
In induction, energy is calculate from the current. Induction resists changes in current in the circuit. When direct current flows through an inductor, a magnetic field is create. As a property of the magnetic field, when the current suddenly increases or decreases, the current in the magnetic field changes in the opposite direction. This prevents or prevents a change in current in the circuit. Induction prevents the instantaneous variation of the current.
AC and DC currents
Like AC for a capacitor and resistor circuit, the voltage (or EMF) will lag behind the current (depending on the capacitance and frequency) because the resistance voltage of the capacitor varies. If a direct current circuit is apply, the current will start to be high and will drop to 0. In this case, the charge on the capacitor increases while the current remains until the potential difference in the capacitor becomes too large compare to the reverse current for electricity.
When alternating current is apply to a circuit with a coil and a resistor, the current will leave a voltage (depending on the inductance and frequency) because the inductance resists changes in current. When direct current is apply, the current starts low and rises to a steady state, like an invert capacitor. This is because the magnetic field in the inductor resists the current surges that occur when the DC is turned on. When the power is off, the magnetic field will cancel the change.
Frequency and inductance of the capacitor
Capacitors are best for transmitting high frequency signals. They can be used to block low frequency signals or noise. The size of the capacitor can change the frequency range of the filter and different capacitor sizes can be combined.
Inductors work best at low frequencies and filter out high frequency signals and oscillations. Inductors can be used in conjunction with capacitors to limit the frequency range in the circuit.
