SLIDER VALUE: 5.4 volts. As letter V [[grows]], letter I [[grows]]. Current now [[10.8]] millamps.
SLIDER VALUE: 3.6 volts. As letter V [[shrinks]], letter I [[shrinks]]. Current now [[7.2]] millamps.
SLIDER VALUE: 600 ohms. As letter R, [[grows]], letter I, [[shrinks]]. Current now [[7.5]] millamps.
SLIDER VALUE: 400 ohms. As letter R, [[shrinks]], letter I, [[grows]]. Current now [[11.3]] millamps.
Scene Summary
In this sim, there are sliders in the Play Area to simultaneously explore two representations of Ohm's Law:
- the equation, V equals I times R, and
- a circuit, two wires connecting a series of batteries to a resistor.
Buttons in the Control Panel mute sound and reset sim.
Right now,
- voltage is [[4.5]] volts
- resistanceis [[500]] ohms
- current is [[9.0]] milliamps
Thus,
- Letter V is [[much larger]] than letter I and [[comparable to]] letter R.
Look sliders to play.
