Here are the answers to the questions based on the provided circuit symbols: 3(a) Identify each of the components whose symbols are labelled IV, V, VII and VIII. • IV: Inductor (or Coil) • V: Diode • VII: Light Dependent Resistor (LDR) • VIII: Alternating Current (AC) Supply 3(b) State the function of each of the components whose symbols are labelled II, III, VI and VIII. • II (Cell): Provides a source of electromotive force (e.m.f.) or electrical energy to drive current in a circuit. • III (Resistor): Limits or opposes the flow of electric current in a circuit. • VI (Light Emitting Diode - LED): Emits light when current flows through it in the forward direction. • VIII (AC Supply): Provides an alternating voltage or current that periodically reverses direction. 3(c) Select a set of components that when connected in series to VI will cause it to light up when the key is closed but goes off immediately. The components needed are a power source, a switch, a capacitor to allow temporary current flow, and the LED itself. The set of components is: I (Capacitor), II (Cell), VI (LED), IX (Switch). 3(d) Draw a circuit diagram using the set of components selected in (c). The circuit diagram should show the cell (II), switch (IX), capacitor (I), and LED (VI) connected in series. The LED must be connected in forward bias with respect to the cell.
