Definition
- Resistance

|
|
Term
|
Definition
- Large metal plates with different length wires and internal contacts
- Changing contact points alters resistance & amount of electricity to lamp
- Big & heavy. Generates lots of heat
- Requires many operators in location not visible to stage
- Load on dimmer must equal dimmer capacity
- Necessitates “ghost load” |
|
|
Term
|
Definition
- Uses electromagnetic forces to create varible currents
- Smaller, more compact – still heavy
- Smoother dimming
- No need for ghost load
- Lots of electric cables running to and from |
|
|
Term
|
Definition
- Uses Silicon controlled rectifier (SCR)
- Small and lightweight
- Allows for greater # of dimmers in smaller space
- Paves way for dimmer per circuit
- Can be controlled remotely
- Operator can be in view of stage with dimmers in a distant location
- With computers, much greater control & flexibility |
