What different kinds of electric circuits exist?

Electric circuits are classified based on how components are connected and how current flows through them. The main types of electric circuits are:

1. Series Circuit

• Components are connected one after another in a single path
• The same current flows through all components
• If one component fails, the entire circuit stops working

Example: Old decorative lights

1. Parallel Circuit

• Components are connected across multiple paths
• Each component gets the same voltage, but current is divided
• If one component fails, others continue to work

Example: Household wiring

1. Open Circuit

• The circuit path is incomplete or broken
• No current flows

Example: Switch turned OFF

1. Closed Circuit

• The circuit path is complete
• Current flows normally

Example: Switch turned ON

1. Short Circuit

• Occurs when current takes a low-resistance unintended path
• Leads to excessive current, which can cause damage or fire

Key understanding:

• Series → One path
• Parallel → Multiple paths
• Open/Closed → Flow condition
• Short circuit → Fault condition

In simple terms:
Electric circuits can be arranged in different ways depending on how current needs to flow and how devices are connected.
