Current Divider Equation

Current Divider Equation: In a parallel circuit, the Current Division in all branches. Thus, a parallel circuit acts as a current divider. The total current entering into the parallel branches is divided into the branches currents according to the resistance values. The branch having higher resistance allows lesser current, and the branch with lower resistance […]

Kirchhoff’s Current Law Definition

Kirchhoff’s Current Law Definition: Kirchhoff’s Current Law Definition states that the sum of the currents entering into any node is equal to the sum of the currents leaving that node. The node may be an interconnection of two or more branches. In any parallel circuit, the node is a junction point of two or more […]

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 (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 […]

Basic Components of Electric Circuit

Basic Components of Electric Circuit: The Basic Components of Electric Circuit consists of three parts: (1) energy source, such as battery or generator, (2) the load or sink, such as lamp or motor, and (3) connecting wires as shown in Fig. 1.2. This arrangement represents a simple Circuit Basics, A battery is connected to a […]

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 […]
