A synchronous motor runs at 600rpm, which of the following case is true?

P = 12, f = 60 Hz

P = 10, f = 60 Hz

P = 8, f = 50 Hz

P= 12, f = 50 Hz

P = 12, f = 60 Hz

P = 10, f = 60 Hz

P = 8, f = 50 Hz

P= 12, f = 50 Hz

Which of the following is the correct relation regarding coupled coils?

M > (L1L2)0.5

M ≤ (L1L2)0.5

M = (L1 + L2)/2

M = (L1 − L2)/2

M > (L1L2)0.5

M ≤ (L1L2)0.5

M = (L1 + L2)/2

M = (L1 − L2)/2
