An voltage subtractor circuit is a circuit that produces an output voltage proportional to the voltage difference of two input signals applied to the inputs of the inverting and non-inverting terminals of an operational amplifier. We can first analyse the part of the circuit connected to the non-inverting input. It act as a potential divider, […]
An amplifier is a device that increases the strength of the input signal. An operational amplifier also known as Op Amp amplify the voltage. It is a three-terminal electronic device, having two input terminals, a inverting terminal marked by the “-” sign and a non-inverting terminal marked by the “+” sign. The third terminal is […]
Inductors are passive components that store energy through magnetic field. It creates a magnetic field when a current is passed through them. Inductance is the tendency of electrical conductor to oppose a change in electrical current flowing through it. The current flowing through the inductor cannot mutate because the inductor generates a electromotive force that […]
A capacitor is a device used to store electrical charge and electrical energy. The voltage at both ends of the capacitor cannot mutate because it takes time for capacitors to charge or discharge. The capacitance of the capacitor is defined as the ratio between the maximum charge that is abled to be stored on the capacitor to the […]
A resistor is a passive component that limits or regulates the electric current in a circuit. The resistance is a measure of how difficult it is to pass current through a wire or component. It depends on the resistivity of the material. Resistance is defined as the ratio of the voltage to the current. It is directly proportional to the length of the material and inversely proportional to the cross-sectional area of the material. […]
