Determining the resistor value for lighting LEDs is simple and straightforward, but we must take into consideration the color of the LED as well as the wattage rating of the required resistor, and the number of LEDs in the circuit. We hope reading How to Calculate Resistor Value for LED Ligh...
Young electronic hobbyists and enthusiasts are often confused and wonder how to calculate LED and its resistor in a circuit, since they find it difficult to optimize voltage and current through the group of LEDs, required to maintain an optimum brightness. Contentshide 1Why we need to Calculate ...
To get this to happen you can use a transistor or relay with second, larger resistor connected directly to the cap and with nothing else connected yet, then wait for a time until the cap charges, then disconnect that second resistor and connect the original circuit and it will be connected...
Explain why the actual resistance of the resistor is irrelevant. 1. Explain how you would expect charge to vary with potential and why? 2. Explain how you would expect charge to vary with capacitance and why? 3. Describe the relationship between capacitanc...
