同频率的交流电 压和交流电流的最大值相量式分别为：m=2202220V，m=52220V，则电压与电流的相位关系是（）/ananas/latex/p/2046/ananas/latex/p/509/ananas/latex/p/303210/ananas/latex/p/2047/ananas/latex/p/509/ananas/latex/p/1897
举一反三
- 在i=5sin（ωt+36.9°）A对应的电流相量是/ananas/latex/p/509/ananas/latex/p/2047
- 电压u=220(314t+60°）V，下列交流电压的相量式中正确的是。/ananas/latex/p/509/ananas/latex/p/512
- 已知()=0.4，则()=( )/ananas/latex/p/152/ananas/latex/p/278/ananas/latex/p/847/ananas/latex/p/281/ananas/latex/p/152/ananas/latex/p/4781/ananas/latex/p/7419/ananas/latex/p/6547
