Circiuts

• A circuit is an electrical pathway that allows current to flow.
• In a parallel circuit, multiple paths exist between the power source and ground.
• In a series circuit, all components are connected end-to-end in a single loop.
• The two main types of circuits are series circuits and parallel circuits.
• In a parallel circuit, there are two or more paths for the current to follow.
• In a closed circuit, electrons can move freely from one end of the wire to the other.
• The components in a series circuit are connected end to end, so there is only one path for the current to flow through.
• Series-parallel circuits contain both series and parallel connections.
• When a switch is closed, the contacts touch each other, allowing current to flow through them.
• When a switch is open, no current will pass through it because there is no complete path for the current to travel along.
