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

Understanding of independent and dependent sources

-
  In an electrical circuit, a source is a device that provides electrical energy to the circuit. Sources can be classified as either independent or dependent. An independent source is a source that can produce an electric potential (voltage) or an electric current without being influenced by the circuit. Examples of independent sources include batteries, generators, and power supplies. A dependent source is a source that produces an electric potential or an electric current based on the voltage or current in the circuit. Examples of dependent sources include transistors and thermocouples. The behavior of a circuit with an independent source is determined by the characteristics of the source and the resistive elements in the circuit. The circuit will operate the same way regardless of the current or voltage in the circuit. The behavior of a circuit with a dependent source is more complex, as the source produces a current or voltage that is dependent on the current or voltage...

Understanding of series and parallel resistors

-
  In an electrical circuit, resistors can be connected in series or in parallel. The connection determines how the resistors behave and how they affect the current and voltage in the circuit. In a series connection, the resistors are connected end-to-end, so that the current flows through each resistor in turn. In a parallel connection, the resistors are connected side-by-side, so that the current can flow through multiple resistors at the same time. The relationship between the resistance, current, and voltage in a circuit with resistors connected in series is given by Ohm's law: V = IR Where V is the voltage across the resistors, I is the current through the resistors, and R is the total resistance of the circuit. The total resistance of a circuit with resistors connected in series is equal to the sum of the individual resistances: R = R1 + R2 + R3 + ... The relationship between the resistance, current, and voltage in a circuit with resistors connected in parallel i...
