State Ohm’s law. [1 MARK]

Ohm’s Law is a fundamental principle in electrical engineering and physics that describes the relationship between voltage, current, and resistance in an electrical circuit.

It is represented as follows:

V = I × R

where:

• V represents the voltage (in volts, V) across a component in the circuit.
• I represents the current (in amperes, A) flowing through the component.
• R represents the resistance (in ohms, Ω) of the component.

Ohm’s Law asserts that the current passing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance. In other words, if you increase the voltage across a component with constant resistance, the current will also increase proportionally.

Conversely, if you increase the resistance while keeping the voltage constant, the current will decrease proportionally.
