Definition of a multimeterThe utility model relates to a magneto-electric instrument with a rectifier that can measure various electrical parameters such as AC, DC current, voltage and resistance.Components of a multimeter Header:The head of a multimeter is a sensitive galvanometer. The dial on the watch head is printed with a variety of symbols, scales and values. Selector switch:The selection switch of the multimeter is a multi-gear rotary switch. Used to select measurement items and ranges St

What are Kirchhoff's Laws?Kirchhoff’s Laws DefinitionKirchhoff’s laws describe how current and voltage distribute in an electrical circuit, essential for analyzing circuit behavior.Kirchhoff’s Laws Classification Kirchhoff Current Law (KCL):KCL states that at any junction in an electrical circuit, the total current entering equals the total current leaving the junction. Kirchhoff Voltage Law (KVL): KVL states that the sum of all voltage gains and drops around any closed loop in a circuit is zero

What is Millmans Theorem?Millman’s Theorem DefinitionMillman’s theorem is defined as a method to simplify circuits with multiple parallel voltage or current sources into a single equivalent source.Application to Voltage Source CircuitsMillman’s theorem simplifies circuits with only voltage sources in parallel into an equivalent voltage source with a series resistance.Equivalent Voltage CalculationThe equivalent voltage (VE) is calculated using the theorem, representing the Thevenin voltage.Appli

What is a Schmitt Trigger?Schmitt Trigger DefinitionA Schmitt Trigger is a comparator circuit that uses hysteresis through two threshold voltages to stabilize signal transitions.Circuit DesignSchmitt Triggers can be designed using operational amplifiers or transistors, and are available in inverting and non-inverting forms.How does a Schmitt Trigger work?The Schmitt trigger maintains a low output until the input exceeds the upper threshold (VUT). It then switches to a high output, which persists
