Capacitance in Series

When working with individual capacitors in electronic circuits, it is essential to understand their behaviour and effects. For example, in a series arrangement, the positive plate of one capacitor is connected to the negative plate of the next capacitor in line. This unique connection impacts the ci

Resistance in Series Explained

Resistance in series refers to the arrangement of individual resistors end to end in a circuit so that the current flows through each resistor. In this configuration, the total resistance (R) of the circuit is equal to the sum of the individual resistances, also known as the equivalent R. To calcula

Voltage Drop Explained

Voltage drop (VD) occurs when the voltage at the end of a run of cable is lower than at the beginning. Any length or size of wires will have some resistance, and running a current through this dc resistance will cause the voltage to drop. As the length of the cable increases, so does its resistance

Wiedemann Franz Law

Wiedemann-Franz law is the law which relates the thermal conductivity (κ) and the electrical conductivity (σ) of a material which consists of somewhat freely moving electrons in it. Thermal Conductivity (κ): It is the degree (measure) of capacity of a material to conduct heat. Electrical Conductivit

Faraday’s Laws of Electromagnetic Induction: First & Second Law

What is Faraday’s Law Faraday’s law of electromagnetic induction (referred to as Faraday’s law ) is a basic law of electromagnetism predicting how a magnetic field will interact with an electric circuit to produce an electromotive force (EMF). This phenomenon is known as electromagnetic induction. F

Lenz’s Law of Electromagnetic Induction: Definition & Formula

What is Lenz’s Law? Lenz’s law of electromagnetic induction states that the direction of the current induced in a conductor by a changing magnetic field (as per Faraday’s law of electromagnetic induction ) is such that the magnetic field created by the induced current opposes the initial changing ma

Fleming’s Left And Right Hand Thumb Rules Explained

What are Fleming’s Left And Right Hand Rules? Whenever a current carrying conductor comes under a magnetic field , there will be a force acting on the conductor . The direction of this force can be found using Fleming’s Left Hand Rule (also known as ‘Flemings left-hand rule for motors’). Similarly i
