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: ...

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: ...

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.

Calculating the interest rate using the present value formula can at first seem impossible. However, with a little math and some common sense, anyone can quickly calculate an investment's interest ...
