8/01/2019 · Hi viewers, subscribers in this video I'm showing in this how to find out value of resistors,Ohm. Subscribe, Like, Comment, Share. Thanks for watching. Stay on watching my channel..... After we found the power that the resistor requires we have to find a resistor that will handle that power. And also temperature will degrade the capacity of the resistor to handle power.For example a thin film resistor will handle 80% of power dissipation at 85 degrees Celsius and 50% at 100 degrees Celsius.
How do I calculate the resistor value for this circuit
Once the resistor value has been modified, locate the .op button on the far right of the tool bar. (if LTSpice is not maximized, you may not see this button, so expand to window).... Selecting resistor values traditionally has been a manual process where the calculated value is matched to a real value in a printed lookup table. The Microsoft Excel add-in presented here automates the process by implementing a single user-defined function with an integrated lookup table.

How To Find Resistor Value
Calculate the resistor value necessary to drop the current to a certain amperage by using Ohm's Law. If you have a 12-volt battery and want to power an LED (Light Emitting Diode) that requires a 0.5 amp current, you would calculate the value of the needed resistor by using the same equation:
- and entering the voltage across the resistor and the current through the resistor for the V and I values respectively. To determine the minimum resistance value required, we need to know the largest possible voltage drop across the resistor along with the smallest maximum current through the resistor.

- "Who Else Wants to Discover the Step by Step Secrets To Find Out The Value of A Burnt Resistor Fast? " Dear Electronic Repairers, How many of you have encountered a resistor that was burnt till you can’t even recognize the colour band and unable to measure the value?
- 5/07/2011 · So the resistor value must be low enough so that the input logic voltage level is met, while the input bias current is passing through the resistor. That gives you an upper bound on the reisistor value, and you'll choose something to give you 2x or 4x margin or so.
