Detect small capacitors below 10pF: Because the capacity of fixed capacitors below 10pF is too small

According to the structure, it is divided into three categories: fixed capacitors, variable capacitors and trimmer capacitors.

Mark directly with numbers and unit symbols. For example, 1 represents 1 microfarad, and some capacitors use "R" to represent the decimal point, such as R56, which represents 0.56 microfarad.

Let's start with the structure of the capacitor. The simplest capacitors are constructed with plates at both ends and an insulating dielectric (including air) in between.

Two conductors that are close to each other with a non-conductive insulating medium sandwiched between them form a capacitor.

Remove the protective cover and inspect the contact surfaces for dirt and burns. If there is dirt, wipe the contact surface with a relatively clean paper.

Since the gear ratio of the generator to the engine is fixed, the speed of the generator will vary with the speed of the engine.
