Ohm's Law Board

Description:

It has lengths resistors equal to one meter, fixed on an insulating plate making conditions of potential difference measurements, electrical resistance and electrical current intensity in lengths of 20 cm.

Composition:

– 01 60x30cm metal plate with leveling feet;
– 25 connection terminals;
– 01 wire nickel-chromium Ø0,720mm x 1m;
– 01 wire nickel-chromium Ø0,510mm x 1m;
– 01 wire nickel-chromium 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 connecting cables: 02 black, 02 red and 01 blue;
– 02 Multimeter.

Studies:

– Ratio between voltage and current of electric current.
– Ratio between length and electrical resistance of the resistor.
– Ratio between electrical resistance and area of the straight section of the resistor.
– Ohmic resistors and not ohmic resistors.
