WebIf we plug those times into the definition of power, we'll find that the power output of the weightlifter on the right during his lift is 1,960 joules per second. And the power output of the weightlifter on the left during his lift is 653 joules per second. A joule per second is named a watt, after the Scottish engineer James Watt.
WebA higher joule rating indicates a higher level of protection for your devices. Clamping voltage: The clamping voltage indicates how much voltage the surge protector will allow to pass through before it starts diverting the excess energy. A lower clamping voltage rating provides increased protection against power surges. hillside goat dairy eighty four paWebWhile the joule is the SI base unit for energy, when speaking in real-world terms, we often use the kilowatt-hour (kWh) instead.
