However, for some loads, even this circuit might be an improvement over a simple resistor. Suppose you had a black box instead of an LED. Because of lightbulbs or motors or something inside of it ...

Resistors are one of the most basic yet crucial components in all electronic devices, but what do they actually do, and how ...

You have behaviors. You ride a bike.” It’s similar in the circuit. Each resistor adjusts itself according to a simple rule, but collectively they “find” the answer to a more complicated ...

That is, a 1 KΩ and a 2 KΩ resistor in series will draw as much ... you can also measure reactance using a similar circuit. As a simple thought experiment, then, imagine that Rd=1.

All in all, these problems preclude using a simple resistor to make a current source ... drop across the LEDs (within the limits of the circuit). This circuit is adequate, but not efficient.

Messing around with Arduino can lead to some fun projects — like simple electronic games ... for controlling the current in an electrical circuit. This is particularly important if your project ...

For many years, we have been employing a very simple approach to reduce ... simply connected to ground, the relay circuit draws around 58 mA. With the resistor/capacitor addition the steady ...
