Simple schematic diagrams

What is a closed circuit?

• A circuit that is open and does not allow electricity to flow.

• A complete circuit that allows electricity to flow.

• A circuit that only works with batteries.

• A circuit that is broken and cannot function.

What does an open circuit mean?

• An open circuit is a circuit that is not complete, meaning electricity cannot flow.

• An open circuit allows electricity to flow freely without any resistance.

• An open circuit is a circuit that is fully connected and operational.

• An open circuit is a circuit that has a short circuit condition.

What is the difference between series and parallel circuits?

• In a series circuit, components are connected one after another, while in a parallel circuit, components are connected alongside each other.

• In a series circuit, components are connected alongside each other, while in a parallel circuit, components are connected one after another.

• In a series circuit, all components share the same voltage, while in a parallel circuit, each component has its own voltage.

• In a series circuit, the total resistance is the sum of individual resistances, while in a parallel circuit, the total resistance is less than the smallest individual resistance.

What is the function of a bulb in a circuit?

• A bulb converts electrical energy into light energy.

• A bulb stores electrical energy for later use.

• A bulb regulates the flow of electrical current.

• A bulb amplifies electrical signals.

What are the main components of a simple schematic diagram?

• Battery, switch, bulb, wire.

• Resistor, capacitor, diode, transistor.

• Power supply, fuse, relay, inductor.

• Microcontroller, sensor, actuator, display.

What is the role of wires in a circuit?

• Wires insulate the components of a circuit to prevent electricity flow.

• Wires connect the components of a circuit and allow electricity to flow between them.

• Wires are used to store electrical energy in a circuit.

• Wires act as resistors to control the flow of electricity in a circuit.

What is the significance of schematic symbols in circuit diagrams?

• They represent different components in a circuit, making it easier to understand and construct the circuit.

• They are used to measure voltage and current in the circuit.

• They indicate the power supply type used in the circuit.

• They show the physical layout of the circuit components.

What does it mean for a circuit to be 'short-circuited'?

• A short circuit occurs when electricity takes an unintended path, often leading to excessive current flow and potential damage.

• A short circuit is when a circuit is intentionally designed to have low resistance.

• A short circuit happens when a circuit is overloaded with too many devices connected.

• A short circuit is a type of circuit that operates at a higher voltage than normal.

What happens if one component fails in a parallel circuit?

• All components stop functioning.

• The circuit is completely broken.

• The other components can still function.

• The voltage across the circuit increases.

What happens if one component fails in a series circuit?

• The entire circuit continues to work normally.

• Only the failed component stops working.

• The entire circuit stops working.

• The circuit becomes more efficient.
