What is Kirchhoff’s current law?
The total incoming current to a junction is equal to total outgoing current from that junction of an electric circuit or In other words the net current flowing at a junction of a circuit is zero.
Faraday’s First Law - Electromagnetic Induction
Whenever a conductor is placed in a varying magnetic field, an EMF is induced. A current is induced when the conductor circuit is closed. This current is named an induced current.
What is mutual induction?
When an electromotive force (EMF) is produced in a coil due to the change in current in a coupled coil, the effect is known as mutual inductance.
What is the Electromotive force (EMF)?
The force which motivates the electrons to flow in a circuit known as electromotive force.
Its unit is volt.
What is Kirchoff's voltage law?
According to this law, the sum of voltages in a closed circuit on a closed path is equal to zero. Σv=0
Ohm’s law
> Accordingly at constant temperature and pressure the current through a conductor is directly proportional to the voltage across the conductor.
I ∝ V
> Constructional resistance is directly proportional to length of conductor and inversely proportional to the cross-sectional area of the conductor.
Lenz law
> Accordingly whatever may be the cause of production the induced EMF opposes its initial cause
