Ohm's law with Cobra4

Principle

The connection between electrical voltage and the resulting current is measured with various test resistors.The quotient of voltage and current is a constant value that characterises the component.

Benefits

  • Flexible experimenting thanks to wireless data transmission
  • No ...

Generation of an alternating voltage, rectification and smoothing

Principle

An alternating voltage is induced in a coil in the (alternating) field of a periodically moving magnet. The characteristic of a diode to allow electric current only to pass in one direction is used to rectify the induced alternating voltage. A capacitor that is connected in parallel ...

The bimetallic switch

Principle

A bi-metal strip comprises two metal strips which are laminated together and have different thermal expansion coefficients. When warmed the strip flexes toward the side with the lower expansion coefficient. In so doing, it can act as a switch in the electric circuit.

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.

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.
