Resistance of wires - dependence on the length and cross-

Principle

The resistance of a short thick wire is different to that of a long thin one.

Benefits

• Flexible experimenting thanks to wireless data transmission
• No additional cable connections between the building blocks needed - clear arranged and quick setup
• Contact safety due to ...

Current and resistance in a parallel connection

Principle

In households, electrical devices are often connected in parallel to different sockets of the same electric circuit. The total current and the total resistance of the circuit can be predicted from the partial resistances.

Benefits

• Flexible experimenting thanks to wireless ...

Current and resistance in a series connection

Principle

Various components in a circuit can be connected in series. The total resistance and the total current can be calculated from the partial resistances of the components.

Benefits

• Flexible experimenting thanks to wireless data transmission
• No additional cable connections ...

The potentiometer

Principle

Many controls on electrical devices are potentiometers. A potentiometer acts as a voltage divider. It corresponds to a series connection of two variable resistors with a centre tap, whereby the sum of the resistance of the two resistors remains constant.

Benefits

• Flexible ...

Charging and Decharging of a capacitor

Principle

Capacitors are devices that can store charge. Here the details of how the charge gets in and out of the capacitor is looked at.

Benefits

• Flexible experimenting thanks to wireless data transmission
• No additional cable connections between the building blocks needed - clear ...

Diodes as electrical valves

Principle

A diode only allows electric current to pass in one direction and blocks the other one to the current. It therefore acts as an electric valve. This enables alternating current to also be usable to pump charge into a capacitor.

Benefits
