Understanding of ohm's law, KVL and KCL

 

Ohm's law is a fundamental principle in electrical engineering that describes the relationship between the current, voltage, and resistance in an electrical circuit. It states that the current through a conductor between two points is directly proportional to the voltage across the two points, and inversely proportional to the resistance between them. Mathematically, it can be expressed as:

I = V/R

Where I is the current, V is the voltage, and R is the resistance.

Kirchhoff's voltage law (KVL) is another fundamental principle in electrical engineering that describes the relationship between the voltages in an electrical circuit. It states that the sum of the voltage drops around a closed loop in a circuit is equal to zero. Mathematically, it can be expressed as:

ΣV = 0

Where ΣV is the sum of the voltage drops around the loop.

Kirchhoff's current law (KCL) is another fundamental principle in electrical engineering that describes the relationship between the currents in an electrical circuit. It states that the sum of the currents entering a node (a point in the circuit where two or more elements are connected) is equal to the sum of the currents leaving the node. Mathematically, it can be expressed as:

ΣIin = ΣIout

Where ΣIin is the sum of the currents entering the node
