R_{ L} = ? and I_{2} = 0

R_{L} is the load (resistance)

The following formulas are used to calculate the characteristic quantities when the circuit in any configuration operates with an open-circuit output.

**Formula 1 **

Input resistance:

V1 / I1 = det h /h22

Where the quantities are defined in table (MA096E).

**Formula 2 **

Input conductance:

I1 / V1 = h22 / det h

Where the quantities are defined in table (MA096E).

**Formula 3 **

Voltage gain:

V1 / V2 = h21 / det h

Where the quantities are defined in table (MA096E).

**Formula 4 **

Penetration coefficient:

V1 / V2 = det h / h21

Where the quantities are defined in table (MA096E).

**Formula 5 **

Direct-transference resistance:

V2 / V1 = h21 / h22

Where the quantities are defined in table (MA096E).
