Energy in Electric Circuits (5.2)

Question 1

What is potential difference (3 marks)

Answer 1

The difference in potential energy between the two terminals of a battery can be quantified as the difference in the electrical potential energy per unit of charge. (V volts)

Question 2

What is an electric field

Answer 2

The physical field that surrounds electrically charged particles and exerts a force on all other particles in the field, either attracting or repelling them

Question 3

Where is the energy required for charge separation provided from in an electrical circuit

Answer 3

The energy for charge separation is provided by a cell or battery.

Chemical energy within the cell is transformed into electric potential energy and stored in an electric field
