You have just taken a new position as a trainee electronics technician at a small company that makes a variety of electrical and electronic products. Your Supervisor has given you some introductory training. She has asked you to make a number of circuits to develop your practical skills and understanding of safe working practices. She has also asked that you record your activities and demonstrate knowledge of relevant electrical principles.

Find :

a) You must identify and select: p1

. the correct components to construct each circuit.

. an appropriate safe construction method for each circuit.

b) You must then:

. Construct each circuit in turn. For each circuit, you must measure the:

supply voltage

. potential difference across each resistor.

. current at each position marked as a test point (e.g. TP1).

c) Calculate the theoretical value for:p3

. Each potential difference and current measured in part (b).

. the power dissipated in each circuit.

. a fuse to protect each circuit.

d) Includes 3 circuits.

. Give details of how you chose:

-each component from the given value, p1.

- an appropriate safe construction method for each circuitp145.

. Describe how you took the measurements in part (b). Use diagrams/photographs if appropriate.

. Record the measurements taken in part (b) for potential differences and currents p3 m2.

Show all your work for the calculations for part (c) to find the theoretical values for each circuit.

. Include conclusions that you can make related to resistors connected in series and parallel.p2
