<p>In the following signs, we have 高压电 (high voltage) and 低压电 (low voltage).  <a href="https://www.chineseconverter.com/en/convert/chinese-to-pinyin" rel="nofollow noreferrer">Chinese Converter</a> gives the pinyin: gāo yā diàn and dī yā diàn (this has been wrong in the past).

From bing, 电压: voltage, electric tension, electric pressure. It seems that 电压 is translated from **electric pressure**, so 高压电 literally means **high pressure electric**.

# What is the correct tone for 压 in 高压电 (high voltage) and 低压电 (low voltage)?

(Asked by: username_0 on 2017-06-10)

In the following signs, we have 高压电 (high voltage) and 低压电 (low voltage). [Chinese Converter](https://www.chineseconverter.com/en/convert/chinese-to-pinyin) gives the pinyin: gāo yā diàn and dī yā diàn (this has been wrong in the past). However, [Dict.cn](http://dict.cn/%E5%8E%8B) and [WrittenChinese.com](https://dictionary.writtenchinese.com/worddetail/ya/6667/1/1) assign 压 two possible tones: yā (first tone) or yà (fourth tone). So I don't know which is correct.

**Question**: What is the correct tone for 压 in 高压电 and 低压电?

Actually, both tones are possible. In different rigon in China, people have different pronunciation of the same word. However, yā is the official pronunciation of "压". And it used in more scene than yà.
