From someone who made the screen trippier and trippier as a kid until he Icarus’d it, strong magnets taped to a drill bit and spun at high speed around the screen can degauss it. But this type of information basically has no application anymore
Speaking of Icarus, the Parker Solar probe has made its closest approach to the sun this morning. It cut contact (as planned) on Monday and it’s probably reconnecting on Friday. That little guy is great. 3.8 million miles from the surface at 430,000mph.
110/120 is the voltage. That’s irrelevant to the amperage, which is somewhat standardized as 15a on normal outlets and 20a on kitchen or garage outlets.
Extension cords do not have fuses/circuit breakers. That’s found in some power strips but it’s neither required nor necessary with proper use.
And I can literally only reach my car with a welder if I use an extension cord…
The risk of daisy-chaining power strips is it become very easy to overload it, so yes, a circuit breaker would be nice as fire protection. 17 phone chargers would be fine but heating appliances will overload it fast. With no internal breaker, it’s easy to cause a fire with really cheap strips but, if life was ideal, they’d all be made to handle 20a loads like the receptacle in the wall.
The risk of daisy-chaining extension cords is the extra resistance incurred at each connection. There’s a varying amount form the imperfect contacts and a varying amount from pulling the cords apart over the time of device use. If you keep burning plugs with your yard care equipment, it’s probably not normal. It’s usually from partially unplugged cords trying to carry 10-20a across half the planned plug contact. You can readily buy 10-16 awg cords in 110v markets. It’s up to you to determine the appropriate gauge. In an ideal world, they’d all be 10awg. But we don’t have that, we have a world where you can actively choose to save money and increase risk.
