Resistance

Different types of resistance

Swatch resistors

Were gathered in a sample set of resistors in common use. In them you can see the color code corresponding to its value.

Code resistances

It has a small board containing the color code used to identify the value of a resistor. In the same corresponding to the tolerance bands colors are also shown.

Resistor combination of different materials, length and diameter

This set of different strengths can be used to measure each of them by means of a ohmmeter and make comparisons in relation to its length and diameter.

Decadal resistance box

It has a decadic resistance box in which you can see the internal structure thereof.

Merchandise

Transparent bulbs are available in different power in which students can see the difference and appreciate filament bulbs so as resistors.

Resistors in Series

Connecting flashlight bulbs of equal power in series

It has set of connectors allowing small bulbs in series, which are useful for the study of the characteristics of this type of circuit.

Connecting bulbs of different power flashlight series

It has set of connectors allowing small bulbs in series, which are useful for the study of the characteristics of this type of circuit.

Series connection of everyday bulbs of equal power

Bulbs are available everyday of equal power, which can be connected in series and through their behavior study this kind of circuits.

Series connection of bulbs of different power everyday

Bulbs are available everyday of different power, which can be connected in series and through their behavior study this kind of circuits.

Resistors in parallel

Connecting flashlight bulbs of equal power in parallel

It has set of connectors allowing small bulbs in parallel, which are useful for the study of the characteristics of this type of circuit.

Connecting flashlight bulbs in parallel different power

It has set of connectors allowing small bulbs in parallel, which are useful for the study of the characteristics of this type of circuit.

Parallel everyday light bulbs of equal power

Bulbs are available everyday of equal power, which can be connected in parallel and through their behavior study this kind of circuits.

Parallel connection of bulbs of different power everyday

Bulbs are available everyday of different power, que can be connected in parallel and Through Their behavior study This Kind of circuits.

Series-parallel connections

Connections bulbs in series and parallel on the same circuit

It has a set of lights everyday, just different power and that series-parallel connections allow to study the behavior of these mixed circuits.

rheostat

Connecting a resistor as fixed resistor

It has a rheostat that can be connected to a light bulb. In the fixed resistor connection as it can be seen that the bulb brightness does not change when you move the cursor rheostat.

Connecting a resistor and variable resistor

It has a rheostat that can be connected to a light bulb. In the connection as a variable resistor can be seen that the bulb brightness varies between a minimum and a maximum, move the cursor to the rheostat.

Connecting a resistor and potentiometer

It has a rheostat that can be connected to a light bulb. The potentiometer is connected as you may notice that the brightness of the bulb may vary from zero to a maximum value by moving the cursor.

resistor Circular

It has a resistor in which the resistance is wound into toroidal. This form corresponds to that used in the graduation ambient lights.

Conductivity of various solutions

Bulbs in series with different solutions

Distilled water, drinking water, sugar water and salt water: different solutions are used. Through the brightness of bulbs connected in series with them can be seen the conductivity of different solutions.
