Simple Circuit Design: A Light-Emitting Diode (LED) Circuit
This section details the design of a simple circuit that illuminates an LED. This illustrates how basic components work together.
The circuit requires a power source (e.g., a battery), an LED, and a resistor. The resistor is crucial; without it, too much current would flow through the LED, causing it to burn out. The resistor limits the current to a safe level.
- Identify Components: We need a battery (providing voltage), an LED (to produce light), and a resistor (to limit current).
- Choose Component Values: Let’s assume a 5V battery and an LED with a forward voltage drop of 2V and a maximum current of 20mA. Using Ohm’s Law (V = IR), we can calculate the required resistor value: The voltage across the resistor will be 5V (battery)2V (LED) = 3V. The resistance needed is R = V/I = 3V / 0.02A = 150 ohms.
A 220-ohm resistor would be a safe choice, providing a margin of safety.
- Connect the Components: Connect the positive terminal of the battery to the longer leg (anode) of the LED. Connect the other end of the LED to one end of the 220-ohm resistor. Connect the other end of the resistor to the negative terminal of the battery. This completes the circuit.
- Test the Circuit: If the connections are correct, the LED should light up. If not, double-check the connections and component values.
