Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I ...

Coming from an IT background to an AM transmitter site might leave you with a world of questions. Mark Persons explains the basics.

A handy nomograph quickly determines the equivalent resistance of two parallel resistors. Although you could use the standard formula and a calculator, the nomograph also lets you easily find ...

When resistors are connected in series, the current through each resistor is the same. In other words, ... Calculate the resistance of this parallel combination.

Learn how to calculate resistance in series and parallel circuits. ... The voltage across each parallel resistor is the same. Hence, the voltage across the \({8}\Omega\) = 6.39 V.

The program generally calculates several parallel combination values that fall well within 0.1% of the desired value. By comparison, a single 1% resistor's nominal value may differ by as much as 1.45% ...

Thevenin's equivalents are useful when analyzing power systems and other circuits where the load resistance may change. To find a circuit's Thevenin source voltage v T , replace the load resistor ...
