## 3.25 `Y`: Admittance

### 3.25.1 Syntax

`Y` xxxxxxx n+ n-- value
`Y` xxxxxxx n+ n-- expression
`.ADMittance` label n+ n-- expression

### 3.25.2 Purpose

Admittance, or general voltage controlled dissipative element.

### 3.25.3 Comments

N+ and n-- are the positive and negative element nodes, respectively. Value is the admittance in Mhos.
The resistor (type `R`) differs from the admittance (type `Y`) in that the resistor is a current controlled element, and the conductance is a voltage controlled element, in addition to the obvious use of conductance (1/R) instead of resistance.
