What are the characteristics of resistor, capacitor and inductor? How can we identify them?

What are the characteristics of resistor, capacitor and inductor? How can we identify them?

This question is more general! These components are easy to distinguish in shape, as long as you have a little electrical knowledge and have done something, you can see it. You can also search the picture on Baidu to know. Of course, different types of resistance, capacitance and inductance have different shapes!
The main difference between them is that they have different effects on the current. The resistance hinders the current, the capacitor can store the charge, and the inductance prevents the current from changing

As for resistors, capacitors and inductors, the following statement is correct
A resistors, capacitors and inductors all hinder AC current
B capacitor is a kind of energy storage element, the larger the capacitance, the more energy
The C inductor has a blocking effect on the AC, so it will heat up and consume energy
D resistor is a kind of heating element. The higher the resistance is, the more heating will be
Still hope to analyze

A correct
B error. The larger the capacitance, the greater the ability to store electrical energy. A capacitor without charge, no matter how large the capacity, no electrical energy can be stored
C error. Inductance value can store and release electric energy without consuming energy
D resistor is a kind of heating element. However, the amount of heating depends not only on the resistance value, but also on the current flowing through the resistor or the voltage applied to the resistor

How to judge whether the circuit resonates?

When the signal source is cut off, the current of the circuit will change;
Self excited short circuit capacitance, the current of the circuit will change
The transistor is connected in the circuit, and then the ammeter is connected after the transistor. If the ammeter pointer changes, resonance will occur, otherwise, no resonance will occur
