I = 12V / 220Ω = 0.0545A
The Golden Rule of Electronics
Voltage (V)
Voltage is the electrical pressure in a circuit, measured in Volts. Imagine it as the pressure in a water pipe.
Current (I)
Current is the flow of electrons, measured in Amperes. It's like the volume of water flowing through the pipe.
Resistance (R)
Resistance is the opposition to flow, measured in Ohms (Ω). It's like narrowing the water pipe.
