Ohm's Law. Set

It has resistors of length equal to one meter, fixed in an insulating plate. It allows to carry out measures of tension, electrical resistance and intensity of electric current in lengths of 25cm.

Composition:

- 01 metal plate 60x30cm with leveling feet;
- 25 connection terminals;
- 01 nickel-chromium wire Ø0,720mm x 1m;
- 01 nickel-chromium wire Ø0,510mm x 1m;
- 01 nickel-chromium wire Ø0,360mm x 1m;
- 01 iron wire Ø0,510mm x 1m;
- 01 copper wire Ø0,510mm x 1m;
- 01 DC power supply, 0 to 30V DC, voltage adjustment, with maximum current of 3A, electronic protection against short circuit, input 127 / 220V AC;
- 05 connection cables: 02 black, 02 red and 01 blue;
- 02 multimeters.

Studies:

- Relationship between voltage and current intensity.
- Relationship between electrical resistance and resistor length.
- Relation between electrical resistance and the cross-sectional area of ​​the resistor.
- Non-ohmic resistors and non-ohmic resistors.
