Voltage Divider Circuit Diagram

Voltage Divider Circuit Diagram: The series circuit acts as a Voltage Divider Circuit. Since the same current flows through each resistor, the voltage drops are proportional to the values of resistors. Using this principle, different voltages can be obtained from a single source, called a voltage divider. For example, the voltage across a 40 Ω […]

KVL Law

KVL Law (Kirchhoff’s Voltage Law): KVL Law states that the algebraic sum of all branch voltages around any closed path in a circuit is always zero at all instants of time. When the current passes through a resistor, there is a loss of energy and, therefore, a voltage drop. In any element, the current always

Voltage Source and Current Source

Voltage Source and Current Source: According to their terminal Voltage Current Characteristics, electrical Sources of Energy are categorized into ideal voltage source and current source. Further they can be divided into Independent and Dependent sources. An ideal voltage sources is a two-terminal element in which the voltage vs is completely independent of the current is

Capacitance Formula

Capacitance Formula: Capacitance Formula is given by any two conducting surfaces separated by an insulating medium exhibit the property of a capacitor. The conducting surfaces are called electrodes, and the insulating medium is called dielectric. A capacitor stores energy in the form of an electric field that is established by the opposite charges on the

Inductance Formula

Inductance Formula | Inductance Symbol: Inductance Formula explains that when a wire of certain length, when twisted into a coil becomes a basic inductor. If current is made to pass through an inductor, an electromagnetic field is formed. A change in the magnitude of the current changes the electromagnetic field. Increase in current expands the

SI Unit of Electrical Resistance

SI Unit of Electrical Resistance: SI Unit of Electrical Resistance – When a current flows in a material, the free electrons move through the material and collide with other atoms. These collisions cause the electrons to lose some of their energy. This loss of energy per unit charge is the drop in potential across the

Power and Energy Formula

Power and Energy Formula: Power and Energy Formula – Power is the rate of change of energy, and is denoted by either P or p. If certain amount of energy is used over a certain length of time, then where dw is the change in energy and dt is the change in time. We can

Current Definition

Current Definition: Current Definition states that there are free electrons available in all semiconductive and conductive materials. These free electrons move at random in all directions within the structure in the absence of external pressure or voltage. If a certain amount of voltage is applied across the material, all the free electrons move in one

Electric Voltage

Electric Voltage: Electric Voltage states that, according to the structure of an atom, we know that there are two types of charges: Positive and Negative. A force of attraction exists between these positive and negative charges. A certain amount of energy (work) is required to overcome the force and move the charges through a specific
