show you the resulting resistor value. Additionally the closest resistor within the E series as well as within the Renard numbers is displayed automatically. As another feature the program can calculate the required resistor value for LED circuits (single LED, series connection, parallel connection)....
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...
A 15 ohm resistor is made from a copper wire of mass 14.2 grams. What is the wire's diameter and length? A 5.30 m length of 2.1 mm-diameter wire carries a 790 mA current when 18.0 mV is applied to its ends. The drift velocity is 2.1 x ...
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...
it needs a chiller and a high amperage constant current driver with no voltage spiking or current overshoot at all, as laser diodes and laser diode array modules are very sensitive beasts that run away without current limiting and soft start., A ballast resistor just isn't good enough to dri...
You could then find out the typical number of volts used by a ceiling fan (by calling the manufacturer or just looking online), multiply the two numbers, and generate an estimate of the wattage needed to run the ceiling fan. 3 Determine resistor wattage. If you want to know wattage of ...
