ELECTRICAL QUANTITIES

DU TITLE: ELECTRICAL QUANTITIES

 

CONTEXT: This unit has been developed in order to be taught at the beginning of the first term. It has been prepared for a 12-student classroom. The students are around 16 years old, their English level is about A2 and all of them have elemental knowledge about electricity.

LEARNING OUTCOMES:

• ·         To know the different kinds of fundamental electrical quantities.
• 
  
• ·         To calculate current, resistance and voltage using Ohm's law in elemental circuits.
• 
  
• ·         To calculate power and energy in basic circuits.
• 
  
• ·         To measure electrical resistance, current and voltage.

 

SUBJECT CONTENT:

• ·         The matter. Electrical charge.
