Six original Cambridge-style questions on circuit symbols: naming components, the rules each symbol carries, reading a simple diagram, and recalling what each component does.
Name the component represented by each of these symbols: (a) a circle with the letter A, (b) a circle with a cross inside, (c) a triangle touching a straight bar.
State how an ammeter and a voltmeter should each be connected into a circuit.
Describe how a thermistor and a light-dependent resistor each respond to a change in their surroundings.
A student wants to draw a circuit with a cell, a switch and a lamp connected one after another. Describe the diagram, and state what the long line and the short line on the cell represent.
State the purpose of a fuse in a circuit, and describe what happens to it if the current becomes too large.
A diode is placed in a circuit so that its triangle points from the positive terminal toward the lamp. State whether the lamp lights, and explain. Then state what happens if the diode is reversed.
Mark this once you have attempted all six and checked your working. It records a Practiced badge on the topic and adds a one-time bonus. Revealing the solutions alone does not count.
