Principle

In current circuits, different components can be connected in series. Total resistance and total current can be calculated from the partial resistances.

Benefits

• Particularly comprehensible and didactically prepared description of experiments (reference to everyday life, etc.) incl. protocol questions.
• Future-oriented teaching: Integration into digital science lessons with tablets or smartphones.
• Increased motivation among students through use of the intuitive measureAPP.
• Increased media literacy.
• No additional cable connections between the modules necessary - clearer and faster set-up.
• contact safety due to puzzle-like interlocking building blocks.
• Hard gold-plated, corrosion-resistant contacts
• Double learning success: electrical circuit diagram visible on the upper side and real components on the lower side

Tasks

• Connect one incandescent lamp in series with another of the same type and interpret the phenomenon that occurs.
• Investigate which laws apply to the total resistance and the total current in the circuit when two resistors are connected in series.

Learning Objectives

Students should learn the relationship between the partial currents of a series circuit and the total current using the measured values they obtain. In addition, they should determine the relationship between partial resistances and total resistance in a series circuit.
