The first video was a simple circuit with a resistor, three switches, and three LEDs in series. When a battery was connected, the LEDs were somehow switched on one at a time.The second video ...

Understanding LED resistors is crucial for circuit design. Find out how to choose the correct resistor to ensure efficiency and longevity in your projects.

Connect a circuit using wire, a 9-V battery, an LED, a resistor, and a microammeter to measure current. Have students note what happens when they complete the circuit first by connecting the leads ...

Of course, the resistor also has to have a sufficient view of the LED. You might use this as a safety light that only works in the dark. A simple circuit, but it just goes to show that we tend to ...

Using properties of a series circuit, the sum of the voltages across the LED and resistor R must equal the supply voltage. \({V_s} = {V_{LED}} + {V_R}\) Now substitute the supply voltage (\(6V ...

Series circuits cannot support LED lights due to high voltage operation." The remainder of the lights are on multiple circuits, which, the site explains, "a lower voltage circuit connection with ...

Resistor values are measured ... for controlling the current in an electrical circuit. This is particularly important if your project uses LEDs, or is complex enough to otherwise require more ...
