Many equipment manufacturers prefer protection circuits combining resettable overcurrent protection devices with upstream fail-safe protection. In this example, R1 represents a ballast resistor used ...

Or voltage variation can occur if an LED in one string is shorted. In Fig. 2, the power-limit circuit is formed by R11, R12, R13, R14, Q11 and Q12.

Discover the step-by-step process of creating a powerful music reactive LED strip circuit in this comprehensive tutorial.

The “two flashing led” circuit is designed for 9 Volts but it works at lower voltages too. In this design we used red leds but by changing the series resistors R1 and R4 you can also use different LED ...

2) LED as a Continuity tester: The above shown circuit is LED as continuity tester. This circuit is used for checking continuity of cables, connectors and switches. When A and B terminals are shorted, ...

The numbers you see on the box don't always work out in real life. LED bulbs do last longer but those claims about five to 10 ...

A small round LED floodlight. Before installing them on the tractor, he tested them on the workbench. Frank was impressed with how much light both fixtures provided, exceeding the brightness of his ...

Midwest Circuits' LED street-light technology shines Published: Jun. 12, 2008, 9:00 a.m. By Sarah A. Rigg Patel ...

The LED is glowing less brightly because play dough has some electrical resistance. The more play dough a current has to pass through in a circuit, the dimmer the LED will glow.

Circuit diagrams like the one below are used to illustrate a circuit’s different components, or parts, and the direction of its current: A switch in a circuit is any component that can open or close ...
