Va :伏安,电压 (伏特、v)* 电流(安培、a),视在功率(容量)的单位。 w :瓦特,电压 (伏特、v)* 电流(安培、a),有功功率的单位。 纯电阻电路,功率因数cosa=1,视在功率等. W(瓦)=va(伏安)×cosφ(cosφ是功率因数) va(伏安)=w(瓦)/cosφ 扩展资料: 瓦的发展历史: 瓦特是以英国科学家詹姆斯·瓦特的名字命名的,詹姆斯·瓦特对蒸汽机的发展做出了. 拖影现象:左va,右ips 适用场景: 中高端商用液晶显示器、文本办公 推荐高性价比va显示器: tn 面板 tn面板,全称twisted nematic(扭曲向列型)面板,由于低廉的生产成本使tn成为. Va是视在功率,w是实际功率~ !w<va ,一般w值是相应“va”值的60%~70%。 1、对于小容量更加熟悉瓦特(w)这个概念,所以小容量一般都用“w”表示容量。 2、超过1千瓦时,用“va”.
