Once the LED turns on, it then has a constant forward voltage across it. Once this accurs, what kind of resistance does the LED have?

what is the normal resistance measurement range for most DMMs?

LEDs produce light by using ____________. Fill in the blank   solar energy electrical energy magnetic energy diode energy

Question 12 To turn on all the LEDS with the instruction "OUT AL, 4D", AL should be first set to FF 55 4D AA

6. Draw a comparator circuit to turn on an LED when the input voltage exceed 5 volts.

10 D1 R1 5V 1K Determine the current flowing through the LED. (assume an LED forward voltage of 2.1 volts)

What is the correct way to measure current in a completed circuit using a DMM? O Connected in series to the circuit being tested. O Connected in parallel to the circuit being tested. Connected across the load device in the circuit being tested. Connected in placed of the load device in the circuit being tested.

The term "controlling light" is defined as follows:

How do CRTs create RGB colour beams?

Let’s assume that in these two pictures, the batteries in the remote control in picture 1 are aligned in parallel, and the batteries in the remote control in picture 2 are aligned in series. What benefit does a battery alignment in a series provide? In parallel?​ Where might you see remote controls with each type of battery arrangement (series and parallel) used?
