I want to do some practical. I have started with LED and resistor
I want to protect LED from high voltage and current
I have following things
bread board
multimeter
power supply
red LED
I need resistor ?
I have attached datasheet for LED
according to datasheet
forward voltage of LED = 2 v
forward current of LED = 20 mA
I know supply voltage = 5.2 v
formula R=V/I
resistance= (supply voltage - voltage drop of LED)/ current throw LED
R=(5.2-2)/ 20 mA
R=3.2/0.020 A
R= 160Ω
can I use 160 Ω resistor?
