Q: What is the standard symbol for a resistor?

A zigzag line — The zigzag line represents the resistance to current flow.

Q: What does the symbol |-| represent in a schematic?

A capacitor — The symbol |-| represents the two parallel plates of a capacitor.

Q: Which symbol represents a single-pole, single-throw (SPST) switch?

A break in a line that can be connected or disconnected — This depicts a switch that can open or close a single circuit path.

Q: What does the symbol of a triangle pointing down (?) often represent?

A ground connection — The triangle pointing down is a common grounding symbol.

Q: What is the typical symbol for a battery?

Two parallel lines of unequal length — The longer line represents the positive terminal, the shorter, the negative terminal.

Q: Which of these symbols is commonly used for an LED (Light Emitting Diode)?

A diode symbol with two arrows pointing outward — The arrows represent the light emitted from the diode.

Q: What is the symbol for an inductor?

A coil of wire — The coil represents the coiled wire of an inductor.

Q: What does the symbol of an arrow pointing towards a bar (|>) represent in a schematic?

A diode — The arrow indicates the direction of conventional current flow in a diode.

Q: What is the standard symbol for a fuse?

A zigzag line with two terminals — The zigzag indicates the fusible element within the device.

Q: What does the symbol representing two crossing lines (with no dot) typically indicate?

Wires that are not connected — Crossing lines without a dot show that wires are not connected at that point.
