How to convert the unit of resistance and capacitance? Is 100 euro 101? It's not that resistance is converted into capacitance, it's that resistance has j and F, capacitance has j, K and Z. How to convert K and ohm of resistance? What's the relationship between F, UF, PF? How to convert? I don't have this concept in my head. It's very vague. I have to do this work again. Please help me,
The above answers are very correct, I add some: 1. The accuracy of resistance is generally 5% and 1%. Of course, there are also high-precision resistance, which is not explained here. 5% resistance is represented by J, and the resistance value is represented by three digits. For example, 101J represents 100 Ω, and the accuracy is 5%. Of course, if you want to describe a resistance, you need to have size and power
