Title: what are volts and amps, and how are they used to calculate watts? Post by: rkbrookover on Sep 6, 2012 I have heard these terms in many applications for years, and get by fixing things without really knowing what they actually are, but I'd really like a very basic/dummy explanation. thanks!
Title: what are volts and amps, and how are they used to calculate watts? Post by: $abood$ on Sep 6, 2012 Using the water analogy, voltage is the pressure while current is the amount of water flowing.
For a purely resistive load, power in watts = voltage in volts x current in amperes If you have reactances due to capacitors and inductors then there's real power and apparent power. Real power is measured in watts, while the latter is in volt-amperes. |
