Ohm's Law

Ohm's Law

Ohm's Law is a fundamental principle in electricity that relates the voltage, current, and resistance of a conductor.

Definition

Ohm's Law states that the current (I) flowing through a conductor is directly proportional to the voltage (V) applied across it, and inversely proportional to the resistance (R) of the conductor.

Mathematical Representation

Ohm's Law can be mathematically represented as:

I = V/R

Where:

• I is the current in amperes (A)
• V is the voltage in volts (V)
• R is the resistance in ohms (Ω)

Key Concepts

• Voltage: The potential difference between two points in a circuit, measured in volts (V).
• Current: The flow of electrons in a circuit, measured in amperes (A).
• Resistance: The opposition to the flow of electrons in a circuit, measured in ohms (Ω).
• Conductor: A material that allows the flow of electrons, such as copper wire.

Applications

Ohm's Law has numerous applications in:

• Electrical circuits: To calculate voltage, current, and resistance in series and parallel circuits.
• Electrical engineering: To design and analyze electrical systems, such as power distribution and transmission systems.
• Electronics: To design and analyze electronic circuits, such as amplifiers and filters.
