Circuit Diagrams Flashcards

All 6 cards in this deck

On the circuit symbol for a cell, which line is the positive terminal?: The longer, thinner line (the short thick line is the negative terminal).
How does the circuit symbol for a battery differ from the symbol for a single cell?: A battery shows two or more cell symbols joined in a line (two or more long/short line pairs).
How is the circuit symbol for a variable resistor drawn?: A rectangle (resistor) with a diagonal arrow drawn through it.
True or false? The circuit symbol for a thermistor is a triangle pointing at a straight line.: False. That is the symbol for a diode; a thermistor is a rectangle with a diagonal line through it that has a short flat end.
How is the circuit symbol for an LED different from the symbol for an ordinary diode?: The LED has two small arrows pointing away from the diode symbol (light coming out).
How is the circuit symbol for a filament lamp drawn?: A circle with a cross (X) drawn inside it.
