An RLC circuit is a simple circuit which forms an alternating current. A resistor (R) and inductor (L) are placed in series to form a feedback circuit. The voltage across the resistors will cause an alternating current to flow through the inductor, and as the current increases, so does the resistance of the circuit. This effect is used in many types of electrical circuits such as motor control. The circuit (shown in the figure below) consists of a number of transistors and a resistor, and is used to demonstrate the operation of a transistor amplifier. The circuit can be used for the demonstration of voltage amplification by means of a transistor amplifier. The circuit used in the implementation of an RF circuit is an example of a tuned circuit. The circuit can be used in many different applications, for example, in the implementation of a low pass filter or band-stop filter.

The impedance triangle is used to determine the value of an electric current flowing in a circuit. The impedance triangle is defined by the relationship between voltage and current. If the circuit is modeled by a simple resistor which can be measured in ohms. Impedance triangle can be drawn by dividing each side of the voltage triangle by its current, I. The voltage drop across the resistive element is equal to I*R, the voltage across the two reactive elements is I*X = I*XL – I*XC while the source voltage is equal to I*Z.
