Worked Solution & Example Answer:Draw the circuit symbol for any three of the electronic components labelled A, B, C or D - Leaving Cert Engineering - Question c - 2018
Step 1
Draw the circuit symbol for A, B, C
Answer
-
Component A: The circuit symbol for an LED is represented as a diode with two arrows pointing away from it, indicating light emission.
-
Component B: The circuit symbol for a fixed resistor is a rectangle, symbolizing the resistance to current flow.
-
Component C: The circuit symbol for a toggle switch is depicted as a break in a line with a lever that can be toggled open or closed.
Step 2
State the function of each of the electronic components
Answer
-
Component A (LED): The LED will light up to indicate current flow in the circuit.
-
Component B (Fixed Resistor): This resistor protects the LED by limiting the current flowing through it, preventing potential damage.
-
Component C (Toggle Switch): The toggle switch is used to turn the current on or off, thereby controlling the flow of electricity in the circuit.
-
Component D (Battery): The battery provides the necessary electricity energy to power the circuit.
