To find the resistance I used the following calculations:

V= (V_{Power Supply} -V_Green_LED)

V= (5–1.85)

V= 3.15

V=IR

R=V/I

R=3.15 V/.025 A

R= 126Ω

✔

This resistance is a minimum resistance. If there were any less resistance the LED would likely fail.

✔

Using the multimeter and testing the resistance range of the potentiometer, the resistance is ≈ 0Ω-9500Ω

✔

The order of the components does not matter. As long as the electronic elements are in a closed loop, each element will affect the system indifferently in any order.

✔

With a nine volt battery I used the following calculations:

V= (V_Battery– V_LED)

V= (9–1.85)

V= 7.15

R= V/I

R= 7.15 V/ .025 A

R= 286Ω (Minimum Resistance)
