Example: a resistor has a stated value of 100Ω and a tolerance of 10% Calculate the tolerance range 10% of 100Ω = (10÷100) × 100Ω = 10Ω Determine the minimum and maximum resistance values: ...

To calculate resistor values, we need to use Kirchhoff's Law: The sum of currents into a node is zero. Considering the node at the junction of the three resistors, we can write: ...

Using standard 1%-resistor values, a second program, RPar2a.exe, click here, checks and displays all appropriate combinations that generate a desired parallel resistor's value.

When a resistor is connected to the two alligator leads, the Propeller goes through a lookup table and finds a resistor value matching the number coming from the ADC.

If there’s one thing that will surely blind us, its reading resistor color bands. It doesn’t help that red looks exactly like orange, brown and black are indistinguishable, and differen… ...
