Instructions: This worksheet will guide you through various aspects of electricity, including calculations, circuit analysis, and understanding electrical components. Follow the instructions for each activity to enhance your understanding of electricity.

Understanding Electrical Circuits

Study the circuit diagram provided and answer the questions below. Pay attention to the components and their connections.

1. Identify the type of circuit shown (series or parallel).

2. Name the components labelled A, B, and C.

3. Explain the function of component B.

Ohm's Law Calculations

Use Ohm's Law (V = IR) to solve the following problems. Show all your working clearly.

1. If the current through a resistor is 2 A and the resistance is 5 Ω, what is the voltage across it?

2. A circuit has a voltage of 12 V and a resistance of 6 Ω. Calculate the current flowing through the circuit.

3. Determine the resistance if a current of 3 A flows through a component with a voltage of 9 V.

Power and Energy in Circuits

Calculate the power and energy in the following scenarios using P = IV and E = VIt. Show your calculations clearly.

1. A device operates with a current of 4 A and a voltage of 10 V. Calculate the power consumed.

2. How much energy is used by a 60 W bulb in 2 hours?

3. If a heater uses 2400 J of energy in 10 seconds, what is the power rating of the heater?

Series and Parallel Circuits

Compare the characteristics of series and parallel circuits. Use the table to summarise key differences.

Characteristic	Series Circuit	Parallel Circuit
Current	Same through all components	Different in each branch
Voltage	Divided among components	Same across all branches

Analysing I-V Characteristics

Examine the I-V characteristics of different components. Use the graph to answer the questions.

1. Describe the I-V characteristic of a resistor.

2. How does the I-V curve of a diode differ from that of a resistor?

3. What happens to the current when the voltage is increased in a filament lamp?

Static Electricity Concepts

Answer the following questions about static electricity. Consider the causes and effects of static charges.

1. What causes static electricity?

2. Describe a real-world application of static electricity.

3. Explain how static electricity can be a hazard in certain situations.

Extended Writing: The National Grid

Write an essay discussing the importance of the National Grid. Include its role in electricity distribution and its impact on society.
