What is the Dimensional Formula of Inductance?
The dimensional formula of inductance is [ML2T−2A−2]. In this article, we will derive this dimensional formula of inductance. What is a Dimensional Formula? The dimensional
Inductance Formula With Solved Examples
The inductance formula calculates the inductance of the inductor. This article describes the inductance formula and how to calculate inductance. When electric current flows through
Torque/Weight Ratio of an Indicating Instrument
The ratio of torque to the weight of the moving part of an instrument is known as a torque/weight ratio. This ratio affects the instrument’s
Relation Between Current and Drift Velocity (Formula, Derivation, Diagram)
When an electric field is applied to a conductor, free electrons begin to move slowly in the opposite direction of the field. The average velocity
Quality Factor or Q-Factor of a Resonant circuit
The Quality factor or Q-Factor of a resonant circuit can be defined as the measurement of “quality” or “betterness” of a resonant circuit as far
Fleming’s Left Hand Rule and Right Hand Rule
In this article, we will learn about two fundamental Fleming rules given by John Ambrose Fleming, known as Fleming’s Left Hand Rule and Fleming’s Right
What Is a Dry Contact in Electrical? Definition, Working & Uses
A dry contact is an electrically isolated switch or relay contact that does not provide its own voltage to the connected circuit. The external circuit
Lithium Ion (Li-ion) battery Charging
Lithium batteries necessitate a charging algorithm that upholds a constant current constant voltage (CCCV) during the charging process. In other words, a Li-Ion battery should
RC Charging Circuit and RC Time Constant
