### What is resistor?

The resistor is basically two terminal passive component which opposes the flow of current in the circuit. Resistor controls the current flowing through the circuit.

### What is resistance?

The value of resistor is called resistance. Resistance is measured in ohm. When we say resistor value is 10k means the resistance of that resistor is 10k. Resistor with resistance is shown in below example.

### Resistor in series

When two or more than two resistors are connected in series then overall resistance of the circuit is the sum of the resistance of all resistors. Example of resistor in series is shown below.

### Resistor in parallel

When two or more than two resistors are connected in series then overall resistance of the circuit is calculated using the following formula. Example of resistor in parallel is shown below.

### What is inductor?

Inductor is the circuit element that stores energy in the form of magnetic field.

### What is inductance?

The value of inductor is called inductance. Inductance is measured in Henery(H). Example of inductor is shown below.

### Inductor in series

When two or more than two inductors are connected in series then overall inductance of the circuit is the sum of the inductance of all inductors. An example of inductor in series is shown below.

### Inductor in parallel

When two or more than two inductors are connected in parallel then overall inductance of the circuit is calculated by using the following formula. An example of inductor in parallel is shown below.

### Power in inductance

Power in inductance is calculated by using the following formula.

### Energy stored in inductance

Energy stored in inductance is calculated by using the following formula.

### What is capacitor?

Capacitor is the circuit element that stores energy in the form of an electric field,

### What is capacitance?

The value of capacitor is called capacitance. Capacitance is measured in Fared(F).

### Capacitor in series

When two or more than two capacitors are connected in series then overall capacitance of the circuit is calculated by using the following formula. An example of capacitor in series is shown below.

### Capacitor in parallel

When two or more than two capacitors are connected in parallel then overall capacitance of the circuit is the sum of the capacitance of all capacitors. An example of capacitor in parallel is shown below.

### Power in capacitance

Power in capacitance is calculated by using the following formula.

### Energy stored in capacitance

Energy stored in capacitance is calculated by using the following formula.
