I want to make a circuit with 20 LEDs here are the specs of the LEDs that I will be using:
Forward voltage:2.5V
Forward current max.:25mA
Reverse voltage max.:5V
I want to use two AA batteries to power the LEDs I have entered all the details into LED Center calculator. Here is what they said I would need to make the circuit:
Solution 0: 1 x 10 array uses 10 LEDs exactly
+3V
R = 22 ohms
R = 22 ohms
R = 22 ohms
R = 22 ohms
R = 22 ohms
R = 22 ohms
R = 22 ohms
R = 22 ohms
R = 22 ohms
R = 22 ohms
The wizard says: In solution 0:
Many Thanks.

The wizard says: In solution 0:
- each 22 ohm resistor dissipates 13.75 mW
- the wizard thinks 1/4W resistors are fine for your application
- together, all resistors dissipate 137.5 mW
- together, the diodes dissipate 625 mW
- total power dissipated by the array is 762.5 mW
- the array draws current of 250 mA from the source.
Many Thanks.
