# Electromagnetic Induction

Electromagnetic induction is a phenomenon by which electromotive force is produced across a conductor placed in a varying magnetic field. It was discovered by Michael Faraday in 1831 after performing…

# Faraday’s law of electromagnetic induction

Michael Faraday discovered the phenomenon of electromagnetic induction in 1831 which was a major breakthrough and led to the invention of electric motor and generator. Faraday's law of electromagnetic induction…

# Lenz’s law

Heinrich Friedrich Emil Lenz was a Russian physicist, working at the University of St. Petersburg, Russia. He formulated Lenz's law in 1834. This law predicts the direction of the current…

# Resistor color code calculator

Resistors are the basic building blocks of a circuit. They are used in circuits as voltage dividers, current limits, termination for communication links, etc. It is important to know how…

# Maximum Power transfer theorem

In an electric circuit, power flows from the source to the load. The source itself has some amount of impedance which affects the current flow. Therefore, transfer of power depends…

# Superposition theorem

Superposition theorem can be used to find the current or voltage in any circuit containing more than one independent sources. By using this method, we calculate the contribution of each…

# Current Division rule

As we know, in a parallel circuit current divides into all branches. The current flow through each branch is inversely proportional to the resistance offered by each one them. The…
