What else can I help you with?
What resistor to put for 20vott circuit?
That completely depends on the task that you want the resistor to perform, and on where the 20 volts appears in the circuit.
What is different between the resistor and pullup resistor?
A "pull-up" resistor is a resistor used to to perform a specific electronic function - it is not a different type of resistor. A very small current flows through a pull-up resistor so it does not need to be high wattage (1/8 watt is generally fine). The value of a pull-up resistor depends on the resistance of the sensor. If it is simply on or off (no resistance) then a typical pull-up resistor might be 10k ohms.
Is diode an active device?
A passive device is a diode resistor coil and so forth it perform no enhancement to the circuit or act on it.
What is meant by the power rating of a resistor?
A: RATING is a term to describe the capabilities of any components active or passive to perform as designed. Power of a resistor must be rated to safely dissipate within its own power rating
How much work does a battery connected to a 21 ohm resistor perform in one minute?
That completely depends on the voltage of the battery.The energy delivered by the battery and dissipated by the resistor in one minute will be[ 60 x (Voltage of the battery)2 / 21 ] joules
Is Light dependent resistor an example of resistor?
yes, a variable resistor
What happens to the resistor when there are more components?
Adding more components changes how a resistor works. In a series circuit, resistance goes up, slowing current. In a parallel circuit, resistance drops, letting more current flow. The effect depends on how the components are connected.
How do you test to identify a bad resistor?
First you need to know the value of the resistor. Follow the link for a handy resistor calculator After determining the value of your resistor simply test the resistor with an ohmmeter to see if it is at true value. General use should be within + or - 5%
Who invented the resistor?
Otis F. Boykin invented the wire precision resistor and the electrical resistor.
What is the difference between an ohmic resistor and a non-ohmic resistor?
A non-ohmic resistor doesn't have a constant resistance. A ohmic resistor has a constant resistance.
What are resistor values defined by?
Resistor value is defined by the Resistance the resistor offers in Kilo ohms/ohms value given by color codes on the resistor.
What is the function of a cement resistor?
A cement resistor is typically used as a power resistor (a resistor whose power rating is greater than 1 W).
