What does resistance 100 / 1W mean

What does resistance 100 / 1W mean

100 is 100 ohm, and 1W is the maximum power allowed in the circuit, which can be calculated
The maximum voltage at both ends of the resistance in the circuit is: u * u = P * r: u * u = 100 * 1
So the maximum voltage is 10V

Unit conversion! 1 kwh = 1kwh, 1W = 1 J / s, then 1 MJ = kwh

One kilowatt hour, one watt, one joule per second,
So 1 MJ = 10 ^ 6 J
And 1 kwh = 1000 watts * 3600 seconds = 3.6 * 10 ^ 6 joules
So 1 MJ = 10 ^ 6 J = 10 ^ 6 / (3.6 * 10 ^ 6) kwh = (1 / 3.6) kwh = 0.28 kwh
That is 1 MJ = 0.28 kwh

What is the influence of mathematics development on physics?
The typical ones are
1. The influence of analytic geometry on the development of optics in Physics
2. The influence of the establishment of calculus on various branches of physics
In addition, what other mathematical concepts or tools have had a great impact on a certain branch of physics?

Mathematics and physics have never been separated, just like parents and children. Some people say that philosophy is the mother of science, and mathematics is the father of science. However, what we see is that in the development of physics, philosophy plays a guiding role, and sometimes we can get more insight from physics problems
