Light
Bulb. When this
resistive element carries current, it provides
light. Place up to five light bulbs (in sockets) in
the simulation window. With the Select
tool, you can move and rotate
light bulbs, and wire
them to other objects. You attach wires to the
light bulb's two
nodes,
which are indicated by the
yellow
rectangles in Figures
1 and 2. This element has an
alternative
view. The default resistance of the real bulb is about 58 ohms, the typical resistance of the small flashlight bulbs used in many classroom experiments. If you apply more than 6 volts across a real bulb, the bulb burns out and cannot be used again. This corresponds to a current of 102.5 mA. If the current running through an ideal bulb exceeds about 600 mA, the ideal bulb will also burn out. A 1.5 volt battery connected to a 40 ohm bulb carries the default standard current. |
