Electromotive force and Voltage

Learning Objectives:
10.3.2.2 – to explain the difference between electromotive force and voltage drop in the external circuit (in terms of energy);

Task #1

Connecting the ammeter to the circuit, determine the current strength in the electrical circuit;
Taking into account that the current strength in the whole part of the circuit is the same, and using the voltage values in tasks 2 (i) and 2 (iii), determine the resistance values.
What can you say about these resistance values?

Task #2. When watching a video, answer the following questions:

How is the emf determined?
Formula and unit of measurement of EMF
What is voltage?
How is voltage determined?
What is the difference between emf and voltage?
How are the EMF and voltage?
