Although related, voltage ( V ) and power ( P ) are fundamentally different entities. The voltage within an electrical system is a measure of how many joules ( J ) of energy each coulomb ( C ) of charge ( q ) carries with it. Power is a measure of the rate at whichContinue reading “INTRODUCTION TO ELECTRONICS: Electron Volts vs. Kilowatt Hours ( Part 1 )”

ELECTRICITY: Wattage
Q: A parallel electrical circuit connects the electrical outlets located within a room. A 20-A fuse is put into place to protect the circuit from unexpected surges of current ( I ). The voltage drop across each circuit element is V = 120 V. What is the maximum power ( W ) output that canContinue reading “ELECTRICITY: Wattage”
