Circuits (1)
Task 1
Fill in the following gap text with the correct terms from the list given at the end. The terms can not be used at all or multiple times.
A circuit consists of the be >_________________, which are linked by a _________________ and at least one _________________. In such a circuit, _________________, _________________, and _________________ are dependent relationships called _________________. The smaller _________________, the smaller _________________, if _________________ stays the same.
Choices: Resistance R / Voltage source / Ohm’s law / Pythagorean law / Voltage U / Energy Consumption Rate / Electrical Conductor (s) Mass (s) Amperage I / (s) Temperature
