In Resistor combinations: How many values using 1kohm resistors?, Glen Chenier showed us how many combinations of resistor combinations you can get. Many people commented, trying to develop a formula ...

(Fig. 5.) Say you need a 5000 ohm/2-watt resistor to replace a failed one and you need it now! Well, a pair of 10,000 ohm/1-watt resistors in parallel will be an exact electrical equivalent, even if ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

The GWBASIC code at the end of this item is a program called “parallel.bas” which accepts a numerical value of ohms from you the user and returns suggested parallel resistor combinations that most ...

Use Ohms law to relate resistance, current and voltage. In National 5 Physics calculate the resistance for combinations of resistors in series and parallel.

In National 5 Physics examine the current and voltage in series and parallel circuits to formulate rules and determine unknown values.
