OPEN CIRCUIT
An open circuit has a gap or break, so electricity cannot flow. This happens
when a switch is off, or a wire is disconnected, and the devices do not work.
For example, when a light switch is turned off, the circuit is open, and the
bulb does not glow.
CLOSED CIRCUIT
A closed circuit has a complete path, allowing electricity to flow. When a
switch is on, the circuit is closed, and devices like bulbs and fans work.
For example, when a switch is turned on, the circuit is complete, and the
light bulb glows.
SERIES CIRCUIT
A series circuit connects all components in one path. Electricity flows
through each part one after another. If one part stops working, the whole
circuit stops. This is like fairy lights, where one broken bulb can turn off the
whole string.
For example, if one bulb in a string of Christmas lights goes out, all the
lights turn off.
PARALLEL CIRCUIT
A parallel circuit has multiple paths for electricity to flow. Each component
works on its own, so if one stops working, the others still work. This is like
home wiring, where switching off one light does not turn off all the lights.
For example, in a house, if one light bulb burns out, the other lights
continue to work.
