Practical electrical and electronic circuits
Knowledge you need to have:
Knowledge of the circuit symbol, function and application of standard electrical and electronic components: cell, battery, lamp, switch, resistor, voltmeter, ammeter, LED, motor, microphone, loudspeaker, photovoltaic cell, fuse, diode, capacitor, thermistor, LDR, relay, transistor.
For transistors, knowledge of the symbols for an npn transistor and an n-channel enhancement mode MOSFET. Explanation of their function as a switch in transistor switching circuits.
Knowledge of the effect on the total resistance of a circuit of adding further resistance in series or in parallel.
Skills you need to develop:
Measurement of current, potential difference (voltage) and resistance, using appropriate meters in simple and complex circuits.
Application of the rules for current and potential difference (voltage) in series and parallel circuits.
Use of appropriate relationships to solve problems involving the total resistance of resistors in series and in parallel circuits, and in circuits with a combination of series and parallel resistors.
