问题 已知某激励信号u(t)=1.732sin(314t+30°)V,由此可知该信号的有效值、频率及初相角分别为(  )。A.1V,314rad/s,30°B.1.732V,0.02s,30°C.1.225V,50Hz,30°D.1.732V,314rad/s,30°

选项 A.1V,314rad/s,30°
B.1.732V,0.02s,30°
C.1.225V,50Hz,30°
D.1.732V,314rad/s,30°

答案 C

解析 根据已知正弦函数可得:Um=1.732V,ω=314rad/s,φi=30°,所以U=1.225V,T=0.02s,f=50Hz,φi=30°因此,本题答案为C
