1.	Which of the following expression is true in case of open circuit parameters?(a) V1 = Z11 V1 + Z12 I2(b) V1 = Z11I1 + Z12 V2(c) V1 = Z11I1 + Z12 I2(d) V2 = Z11I1 + Z12 I2This question was posed to me in an interview.My question is taken from Open Circuit Impedence(Z) Parameters topic in section Two-Port Networks of Network Theory
Answer» Correct OPTION is (c) V1 = Z11I1 + Z12 I2 To EXPLAIN: The expression relating the open CIRCUIT parameters Z11, Z12 andcurrents I1, I2 and VOLTAGE V1 is V1 = Z11I1 + Z12 I2.
