Exploring Technology: Systems Technology Introduction

Which statement best captures the big idea introduced in Systems Technology?

• Electricity and electronics are about converting heat into light.

• Electricity and electronics focus on the movement of electrons through a given space.

• Electronics only deals with computer programming.

• Electricity is the same as magnetism.

In this lesson, what is the primary goal for understanding circuits?

• To memorize the parts of a computer

• To learn how electricity flows through a circuit to complete a task, such as lighting a light bulb

• To design a new type of battery

• To measure the speed of sound in a wire

Which material property pair is correctly matched based on the objectives?

• Conductor — stops the flow of electrons

• Insulator — allows electrons to flow easily

• Semiconductor — has conductivity between a conductor and an insulator

• Superconductor — has high electrical resistance

Which statement best defines a circuit?

• A device that stores electricity for later use

• A complete circular path that electricity flows through

• A component that turns current on and off

• A diagram of electrical symbols

In the diagram of a simple circuit with a battery, switch, wires, and a light bulb, what must be true for the bulb to light?

• The switch must be open to stop current

• The circuit must be a complete closed path

• Two batteries must be connected in series

• The bulb must be connected in parallel

Which situation represents a series circuit?

• Current splits into multiple branches to reach separate components

• The whole current flows through each component along a single pathway

• Components are not connected in a loop

• Only the switch is connected to the battery

According to the definition of a series circuit, what happens if one component in the single pathway fails (opens)?

• Current keeps flowing through the remaining branches

• Only the failed component stops working

• The entire circuit is interrupted because the single path is broken

• The voltage of the battery increases

Which term correctly matches this description: a general name that includes items like wires, switches, and diodes?

• Circuit

• Component

• Series circuit

• Battery

Which statement best defines a parallel circuit?

• A circuit with one continuous path for current

• A circuit that has two or more pathways for the current to flow

• A circuit that blocks current completely

• A circuit that only uses alternating current

Based on the diagram showing three light bulbs connected side-by-side to a battery, which type of circuit is illustrated?

• Series circuit

• Parallel circuit

• Open circuit

• Short circuit
