| 5F10.00 | Ohm's Law | | |
| 5F10.05 | charge density in circuits | AJP 53(6),552 | Two
demonstrations: first, an electroscope is used to probe the charge density
along a large resistance attached to a 5 KV supply, and second, an example
where current is flowing through a resistance with no change in potential. |
| 5F10.10 | Ohm's law | PIRA 200 | Measure current and voltage in a simple circuit. Change the voltage or resistance. |
| 5F10.10 | Ohm's Law | 5F10.10 | An ammeter, voltmeter, rheostat, and battery pack are connected to demonstrate Ohm's law. |
| 5F10.10 | Ohm's law | Eg-2 | A battery, rheostat, and meters in a circuit. |
| 5F10.10 | Ohm's law | Eo-1 | Measure current and voltage in a simple circuit. |
| 5F10.10 | Ohm's law | Disc 17-19 | Place 2, 4, and 6 V across a resistor and measure the current, then graph. |
| 5F10.12 | water analogy circuit | 30-2.1 | A water analogy illustrates voltage drops across a dc circuit. |
| 5F10.15 | water Ohm's law analog | PIRA 1000 | |
| 5F10.15 | water analog | E-114 | A water analog of Ohm's law. |
| 5F10.15 | IR drop in a wire | E-159 | Clip wires from the terminals of flashlight lamps at various points along a stretched wire carrying 2 - 5 amps. |
| 5F10.20 | potential drop along a wire | PIRA 1000 | |
| 5F10.20 | potential drop along a wire | E-158 | Lecture
galvanometers configured as a voltmeter and ammeter measure current and voltage
on several samples of wire of the same length. A slide clip can be used to
vary length. |
| 5F10.20 | voltage drop along wire | Disc 18-01 | Measure the voltage at six points on a long resistance wire. |
| 5F10.25 | potential drop with Wimshurst | PIRA 1000 | |
| 5F10.25 | potential drop with static machine | E-113 | A
3 m long wood bar is attached at one end to one terminal of a static machine.
The other end can be grounded or insulated. Attach several electroscopes
along the bar to show flow of charge and potential drop. |
| 5F10.26 | high voltage Ohm's law | E-153 | Two ends of a dry stick are attached to a static machine. Measure with an electrostatic voltmeter and microammeter. |
