Session 7

What is the main purpose of a breadboard?

• To permanently fix electronic components

• To easily insert and remove components for prototyping circuits

• To store electronic components

• To convert electrical energy into light

How are the holes on a breadboard connected?

• All holes are connected in a zig-zag pattern

• Top and bottom rows connect horizontally, other holes connect vertically

• All holes connect in a circular pattern

• All holes connect diagonally

What does a switch do in a circuit?

• Changes the color of the LED

• Disconnects or connects the circuit

• Stores electrical energy

• Increases current automatically

What is the function of a resistor in an electronic circuit?

• To limit or regulate the flow of current

• To produce mechanical energy

• To store energy

• To emit light

What does a capacitor do?

• Emits light

• Allows current to flow in one direction only

• Stores electrical energy (has capacity to store energy)

• Converts electrical energy into mechanical energy

What is the main purpose of a diode?

• It stores charge

• It allows electricity to flow primarily in one direction

• It increases the voltage of the circuit

• It converts electrical energy into heat

What does LED stand for?

• Light Emitting Diode

• Light Energy Device

• Low Energy Display

• Large Electrical Device

What happens when an LED is connected to a current source?

• It stores the current

• It emits visible light

• It converts light into current

• It blocks the current

What is the function of a DC motor?

• It converts mechanical energy into electrical energy

• It converts direct current into mechanical energy

• It stores electrical charge

• It controls the direction of current

Why are breadboards useful for beginners and engineers?

• They make it easy to build and test circuits without soldering

• They help change the color of components

• They are used only for storing components

• They are designed to light up LEDs
