Circuit notes
Battery, LED, and Resistor
The Circuit
This circuit demonstrates a 5v battery connected in series with a 330Ω resistor and an LED.
Simulation
- A transient simulation is run for 20 mS with a 200 uS step size.
- The voltage vbat+ is measured between the battery and ground.
- The voltage Vled+ is measured between the LED anode and ground.
- The current Ir is measured through the resistor and LED.
Notes
The LED in this circuit has a voltage drop of . Therefore the voltage drop accross the resistor is
Using Ohm's law we can calculate Ir.
