Voltage of equivalent diode for pentode¶
A pentode has five electrodes: a cathode, an anode, and three grids. The pentode can be replaced with an equivalent diode, and the voltage in the equivalent diode can be calculated.

V = (V_1 + V_2 * D_1 + V_3 * D_1 * D_2 + U_a * D_1 * D_2 * D_3) / (1 + D_1 * (d_a / d_1)^(4/3))
