cell

A single cell that drives a current round a circuit, drawn as its long plate and short one.

cellNode
A single 1.5 V cell, its long positive plate facing along the loop, driving a bulb that glows full.A single 1.5 V cell, its long positive plate facing along the loop, driving a bulb that glows full.

#Attributes

emfAnimatable
Its emf, in volts: a number with an optional prefix letter, or an expression in the scene's parameters. Negative, it drives the other way. Animatable.
circuit-quantity
Default1.5
resistanceAnimatable
Its internal resistance, in ohms. Absent, the cell is ideal. Animatable.
circuit-quantity
Default0
from
In a circuit placed by hand, the grid point its negative end lands on: (x, y).
circuit-point
to
In a circuit placed by hand, the grid point its positive end lands on.
circuit-point
hiddenAnimatable
Taken out of the circuit, which is open where it stood. Animatable.
boolean
Defaultfalse

#Derived attributes

Computed while the element renders — read one with #id.name in attribute position or {{#id.name}} in prose, never set.

currentDerived
The current it drives, in amperes: {{#c.current}}.
voltageDerived
The voltage across its terminals, in volts: its emf less what its internal resistance drops.
powerDerived
The power it gives the circuit, in watts.

  • The long plate is its positive end and faces the way it drives the current: along the loop, or towards to:.
