Answer:
An LED (Light emitting diode) is a current driven device that is very sensitive to voltage an current in order to protect it we will need a resistor.A resistor is a passive two-terminal electrical component that implements electrical resistance as a…Alright we know and have our components now we need one more thing OHM law with a twist.We have to know our voltage source, the led forward voltage and how much current we want to direct to the led bulb.With all those values we will use the formula …The formula is (Voltage of the source(9V) - Voltage forward of LED(2v))/I (current needed for led 0.005A)As you can see in the pictures above we have entered our values and we have 9-2/0,005after doing the calculations we have the result 3500ohm or …
