What does Ohm's Law state about current in a circuit?

Ohm's Law states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance of the conductor. This relationship is succinctly expressed by the formula:

[ I = \frac{V}{R} ]

where ( I ) is the current in amperes, ( V ) is the voltage in volts, and ( R ) is the resistance in ohms.

This means that if the voltage increases while resistance remains constant, the current will also increase. Conversely, if the resistance increases while the voltage remains constant, the current will decrease. Thus, current is directly proportional to voltage (higher voltage results in higher current) and inversely proportional to resistance (higher resistance results in lower current).

Understanding this relationship is essential for troubleshooting electrical circuits and ensuring proper function in electronic systems.
