Resistor
the material we used is resistor because it did`t stop flowing.
It depends on where you are going to use this resistor and what its application going to be. If the circuit you are using can tolerate this then you are fine.
You can only use a resistor to drop a voltage at a constant current. If you know the current, use Ohm's law to calculate the resistor value.
yes you can! you can use a multimeter and a resistor.
You need to use the 250 Ohm resistor in series with HART protocol communication because it acts as a shunt resistor.
No, Using a resistor spark plug with resistor wires can create too much resistance for the ignition system.
resistor is a passive component which opposes the current flowing through a closed ckt. use in opposition of current in ckt .
I wanna use resistor , capacitor and amplifier 7173 for switch alarm circuit. How can i choice resistor and capacitor value because i wanna use 24V DC.
A night light:)
Often we want to easily change a resistor value, so we use a variable resistor. For example, we may want to change the resistor that controls the power sent to a LED, so we can easily make it brighter or dimmer. Often if we use a variable resistor, there is only a very narrow range that is useful. Continuing our example, sometimes we use several LEDs, and we use the variable resistor to set them all to the same brightness. In this case, the resistance range that sets the LED to be twice as bright as the the other LEDs, and the resistance range that sends so much power to the LED that it is permanently destroyed is even less useful. So we add a fixed resistor in series with the variable resistor -- the fixed resistor sets the minimum net resistance, no matter how we turn the knob on the variable resistor. In our example, the addition of the fixed resistor allows us to turn the variable resistor throughout its whole range, and the LED gets brighter and dimmer; without that resistor, a certain range of the knob on the variable resistor would allow so much power to go to the LED that it would be destroyed.
there is less loss of energy through heat, ergo making a more efficient resistor.
