The diagram shows three kitchen appliances connected in parallel to a 230 V mains supply.
State two advantages of connecting appliances in parallel rather than in series.
What is the purpose of the fuse in the live wire?
Explain how a fuse works to protect the circuit.
A label on an air fryer includes this information:
230 V1.8 kW \text{230 V} \quad \text{1.8 kW} 230 V1.8 kWState the equation linking power, current, and voltage.
Use the information on the label to calculate the current in the air fryer during normal operation.
Fuses are available with values of 2 A, 5 A, 10 A, and 13 A. Suggest the most suitable fuse value for the air fryer. Give a reason for your answer.
Some circuits use a circuit breaker instead of a fuse. State two advantages of using a circuit breaker instead of a fuse.
The graphs show some ways that power (PPP) can vary with voltage (VVV) for a fixed resistor.
Which is the correct graph for a fixed resistor?
