For a T-network if the Short circuit admittance parameters are given as y11, y21, y12, y22, then y11 in terms of Hybrid parameters can be expressed as ________

• A. y11 = \(\left(- \frac{h_{21} h_{12}}{h_{11}} + h_{22}\right)\)
• B. y11 = \(\frac{h_{21}}{h_{11}}\)
• C. y11 = –\(\frac{h_{12}}{h_{11}}\)
• D. y11 = \(\frac{1}{h_{11}} \)
