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
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...
Determine resistor wattage. If you want to know wattage of a resistor, you will need to know the voltage (V) and the current (known as I). This is called Ohm’s law.[4] The multiplication formula is voltage multiplied by current, expressed as W=V X I. Sometimes you will see the...
