Basic Answer

4.1 Matching Terms with Statements:

Step 1: Analyze Statements

Carefully read each statement and understand what it describes.

Step 2: Match Terms to Statements

Match each term (Step-up transformer, Step-down transformer, Alternating current, Direct current) with its corresponding statement.

Step 3: Write Answers

Write the letter corresponding to the correct statement next to each term.

Term	Answer	Statement
4.1.1 Step-up transformer	D	It is used at power stations to produce very high voltages.
4.1.2 Step-down transformer	C	It is used to reduce the energy from the main power supply.
4.1.3 Alternating current	A	Electric charges move back and forth transferring energy through the circuit.
4.1.4 Direct current	B	In a circuit that uses cells and batteries, electric charge moves in one direction.

Final Answer: 4.1.1 – D; 4.1.2 – C; 4.1.3 – A; 4.1.4 – B

4.2 Completing the AND Gate Logic Table:

The question is incomplete. A circuit diagram is needed to complete the AND gate logic table. Please provide the circuit diagram. Once provided, I can guide you through creating the truth table. The table will show the output of the AND gate for all possible combinations of inputs A and B. An AND gate outputs a 1 (true) only when both inputs are 1 (true); otherwise, it outputs 0 (false).
