Title: How to indicate power supply
Power supply is an integral component of electronic equipment, and its representation varies in engineering, physics, and daily life. This article will introduce the symbolic representation, unit representation, common types and hot topics of power supply.
1. Symbol representation of power supply
In circuit diagrams, power supplies are usually represented by specific symbols. Here are the common power supply symbols and their meanings:
| symbol | meaning |
|---|---|
| ⏚ | ground symbol |
| +/- | DC power supply positive and negative poles |
| ~ | AC power |
| ⚡ | high voltage power supply |
2. Unit representation of power supply
The electrical parameters of a power supply are usually expressed in the following units:
| parameter | unit | illustrate |
|---|---|---|
| Voltage | Volt (V) | represents potential difference |
| current | Ampere (A) | represents the rate of charge flow |
| power | Watt (W) | Represents energy conversion rate |
| capacity | Ah | Indicates battery storage capacity |
3. Common types of power supplies
Power supplies can be divided into the following categories based on their uses and characteristics:
| type | Features | Application scenarios |
|---|---|---|
| DC power supply | Voltage polarity fixed | Electronic products, battery-powered equipment |
| AC power | Voltage cyclic changes | Household appliances, industrial equipment |
| switching power supply | High efficiency and small size | Computers and communication equipment |
| Uninterruptible power supply (UPS) | Provide backup power | Data centers, medical equipment |
4. Hot topics related to power supply in the past 10 days
The following are the hot topics and discussion points related to power supply in the past 10 days across the Internet:
| hot topics | focus of discussion | heat index |
