两互感线圈同侧并联时,其等效电感量为:
A: \(\frac{{{L_1}{L_2} - {M^2}}}{{{L_1} + {L_2} - 2M}}\)
B: \(\frac{{{L_1}{L_2} - {M^2}}}{{{L_1} + {L_2} + 2{M^2}}}\)
C: \(\frac{{{L_1}{L_2} - {M^2}}}{{{L_1} + {L_2} - {M^2}}}\)
A: \(\frac{{{L_1}{L_2} - {M^2}}}{{{L_1} + {L_2} - 2M}}\)
B: \(\frac{{{L_1}{L_2} - {M^2}}}{{{L_1} + {L_2} + 2{M^2}}}\)
C: \(\frac{{{L_1}{L_2} - {M^2}}}{{{L_1} + {L_2} - {M^2}}}\)
