The correct answer is Battery. 
View all questions of this test
- A battery is a device that stores chemical energy and converts it to electrical energy.
- The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit.
- Energy using an electrochemical oxidation-reduction (redox) reaction.
- The flow of electrons provides an electric current that can be used to do work.
Important Points
Additional Information
Fleming's right-hand rule (generators):
- It shows the direction of induced current when a conductor attached to a circuit moves in a magnetic field. It can be used to determine the direction of current in a generator's windings.
- The thumb is pointed in the direction of the motion of the conductor relative to the magnetic field.
- The first finger is pointed in the direction of the magnetic field. (North to south).
- Then the second finger represents the direction of the induced or generated current within the conductor (from the terminal with lower electric potential to the terminal with higher electric potential, as in a voltage source).
Fleming's left-hand rule (electric motors):
- When current flows through a conducting wire, and an external magnetic field is applied across that flow, the conducting wire experiences a force perpendicular both to that field and to the direction of the current flow (i.e. they are mutually perpendicular).
- The Thumb represents the direction of the Thrust on the conductor / Motion of the Conductor.
- The Forefinger represents the direction of the Magnetic Field.
- The Centre finger represents the direction of the Current.
Key-Points
- The Anode is the negative or reducing electrode that releases electrons to the external circuit and oxidizes during an electrochemical reaction.
- The Cathode is the positive or oxidizing electrode that acquires electrons from the external circuit and is reduced during the electrochemical reaction.
- The Electrolyte is the medium that provides the ion transport mechanism between the cathode and anode of a cell.
- Electrolytes are often thought of as liquids, such as water or other solvents, with dissolved salts, acids, or alkalis that are required for ionic conduction.
