Definition: A type of sensory organ found in some fish that can sense electric fields in the water.

Example: Sharks use their electroreceptors to detect the electric signals produced by their prey.

Definition: A device that shows whether something has an electric charge by using metal parts that move apart or come together.

Example: The scientist used an electroscope to check if the object was electrically charged.

Definition: Related to electric charges that are not moving.

Example: The electrostatic force between the two charged objects caused them to attract each other.

Definition: The branch of physics that studies electric charges at rest and the forces between them.

Example: Electrostatics is important in understanding how charged objects interact with each other.

Definition: Relating to the production of heat using electricity.

Example: The electrothermal system efficiently heats the water for the building.

Definition: Relating to the spread of electrical activity through living tissue or cells without the need for repeated signals.

Example: The electrotonic properties of the nerve cells allow for efficient signal transmission.

Definition: A change in how sensitive and responsive a nerve or muscle is when an electric current flows through it.

Example: The doctor explained how electrotonus affects the nerve's ability to transmit signals during treatment.

Definition: This term describes something that involves the unification of two fundamental forces in physics: the electromagnetic force and the weak nuclear force.

Example: The electroweak theory explains how these two forces are connected at high energy levels.

Definition: A process used to extract metals from their ores by using electricity to deposit the metal onto an electrode from a solution.

Example: Electrowinning is commonly used in the mining industry to recover gold and copper from their solutions.

Definition: A quality of being graceful and stylish in appearance or manner.

Example: The ballroom was filled with elegance, from the beautiful decorations to the graceful dancers.
