Ohm's Law is a fundamental principle in electrical engineering that defines the relationship between voltage, current, and resistance in an electrical circuit. It is stated as:
**V = I × R**
Where:
- **V** is the voltage (in volts, V),
- **I** is the current (in amperes, A),
- **R** is the resistance (in ohms, Ω).
In simple terms:
- Voltage is the "push" that makes the current flow through a circuit.
- Current is the flow of electric charge.
- Resistance is the opposition to the flow of current.
Ohm's Law means that for a given resistor, if you increase the voltage, the current increases. Similarly, if you increase the resistance, the current decreases (for a constant voltage).
For example, if you have a 10V battery and a resistor of 2Ω, the current through the resistor would be:
**I = V / R = 10V / 2Ω = 5A**
This shows that the current flowing through the resistor is 5 amperes.
