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 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
What is a series-parallel circuit?
A circuit with only series connections
A circuit with only parallel connections
A combination of both series and parallel circuits to meet wiring needs
A circuit that operates without a power source
Which description matches a resistor?
A component that stores electric charge for later use
A component that allows current in only one direction
A component that limits or regulates the flow of electrical current in a circuit

A unit that measures electrical power transfer rate
Watts are defined as a unit of measurement for power, specifically the rate at which energy is transferred or used. Based on this, which scenario best illustrates higher wattage?
A device that uses less energy over the same time
A device that transfers energy more slowly
A device that transfers energy at a faster rate
A circuit with lower voltage and no current
