Classification of electrical measuring instruments
The role of electrical instruments is to measure various electrical parameters, such as current, voltage, period, frequency, electrical power, power factor, resistance, inductance, capacitance, etc. Electricians can understand the technical performance and working conditions of the electrical equipment of the circuit by measuring the values of these electrical parameters, so that they can make appropriate treatments and necessary adjustments to ensure the normal operation of the circuit and the safe operation of the equipment.
Basic knowledge of electrician
Electricity is a mature and systematic subject, with a complete set of theories, and it is mathematics that supports this complete set of theories. The theoretical knowledge of electricity used by electricians is also inseparable from the foundation of mathematics.
Elementary electrician knowledge
What is a circuit? The circuit is the path for the flow of current (just like the water flow requires a river, the circuit is equivalent to the river, the current is equivalent to the river water), its role is to transmit and distribute electrical energy, and make electrical energy and other forms of energy mutual conversion (such as electrical energy Converted into heat energy to boil water or heat, etc.).
