The US power distribution plant is considered by analysis the various circuit parameters of both AC and DC power plants to deliver 120V DC voltage to the end user. Using a simplistic approach it is shown that AC power distribution is far more cost effective and indeed safe over DC power generation systems delivering the same power of 750 MW© BrainMass Inc. brainmass.com October 25, 2018, 4:36 am ad1c9bdddf
This solution compares AC and DC power generation.
eat generation and maximum thermal resistance of class A and B
The DC input power, heat generation and maximum thermal resistance of class A and B amplifiers are calculated. We know that the AC output power is 200 Watts, and that the Class A and Class B amplifiers operate with the maximum theoretical efficiency. We also know that the BJT power transistor has a maximum junction temperature of 155 degrees C, if the ambient temperature is 25 degrees C. The calculated results indicate that the Class A amplifier is an enormous power waster in comparison to a class B amplifier.View Full Posting Details
