Electrical Engineering RU-vid Channel is the Online Video learning channel for understanding all fundamental and advance educations about Electrical Components, Principles and all electrical topics.
As we already know, electrical engineering is a branch which combine electricity, electronics and electromagnetism. So, if you are electrical engineer and want to learn more about our field then, subscribe our channel.
This Electrical Engineering channel is a open for all electrical engineers who wants to share those information to our community. It is free to share your all details. Even, you will get all information about Electrical Engineering Interview questions and electrical notes.
Got the relations wrong. When one phase is at its peak, the other two are at an intermediate megative voltage. The big advantage is that the power is provided continuously, unlike two phase home current, where the power provided varies between maximum and 0 120 times a second. (Peaks at both positive and negative parts of the cycle).
Air conditioners (A/C) are often measured in tons because it reflects the amount of heat they can remove from a space in a specific period. One ton of cooling is equivalent to the absorption or removal of 12,000 British Thermal Units (BTUs) per hour. This historical convention originates from the time when ice was used for cooling, and one ton referred to the amount of heat needed to melt a ton of ice in 24 hours. While kilowatts (kW) and kilovolt-amperes (kVA) are also used to measure electrical power, tons provide a more relatable measure for cooling capacity in the context of air conditioning systems. It's a practical way to communicate the cooling power needed for residential and commercial spaces.
i sleep happy knowing multimeteres in very serious grown mens daily use were calibrated/tested next to a cute anime character. they all are clueless but i am the wiser.
