Energy changes in a system, and the ways energy is stored before and after such changes
Question
- A. It increases the current flow.
- B. It converts electrical energy into thermal energy.
- C. It decreases the voltage.
- D. It reduces resistance in the circuit.
Answer
It converts electrical energy into thermal energy.
Explanation
The correct option is "It converts electrical energy into thermal energy.". It converts electrical energy into thermal energy. is right because it directly matches Energy stores and systems: Link electrical work done and current flow to energy transfers in circuits.. The other options are less suitable because they change the required Physics relationship, confuse the relevant energy store or use a distractor that does not answer the question.
Common mistake
Misunderstanding Electrical Work
Students often confuse electrical work done with energy transferred, thinking they are the same concept.
Remember that electrical work done is the energy transferred by an electric current, but they are not interchangeable terms. Focus on how current flow relates to energy transfers in circuits.
