Electrolytic capacitors store higher amount of energy.

• Electrolytic capacitors have higher energy storage capacity compared to other types of capacitors.

• They are commonly used in power supply circuits and audio amplifiers.

• Examples of electrolytic capacitors include aluminum electrolytic capacitors and tantalum capacitors.

Molecules are held together in crystals by intermolecular forces.

• Intermolecular forces, such as hydrogen bonding, electrostatic interactions, and van der Waals forces, hold molecules together in crystals.

• These forces are responsible for the regular arrangement of molecules in a crystal lattice.

• Examples of crystals held together by intermolecular forces include salt (sodium chloride) and quartz.

• The strength and type of ...read more
