Study Notes
Introduction to Circuits Remote Lab
- This lab uses a Circuit Construction Kit DC simulation for remote learning, under a CC-BY 4.0 license.
- The simulation allows exploration of basic electricity concepts in series, parallel, and complex circuits.
- Students can use ammeters and voltmeters to measure current and voltage in various circuit configurations.
- Students should provide reasoning explaining relationships in circuits, including predictions and explanations of circuit behavior.
Prediction Questions
-
Series Circuit: Students predict which bulb will be brightest, explaining their reasoning.
- Parallel circuit is predicted to be the brightest because the bulbs share no power.
-
Parallel Circuit: Students predict the flow of current, explaining their reasoning.
- Series circuits share current so bulbs have less brightness.
-
Complex Circuit: Prediction of current is explained for the complex setup.
- The complex circuit is predicted to have the least current because of the many pathways lightbulbs share the current.
Develop your understanding
-
Light Bulb Circuit Construction: Build a circuit to light up a bulb using the simulation.
- Build a circuit diagram to show how to light up a light bulb.
Measuring Current and Voltage
-
Current Measurement: Current is the flow of charge measured by an ammeter in Amps.
- Ammeter is placed in series in the circuit.
-
Voltage Measurement: Voltage is a potential difference measured between two points by a voltmeter in Volts.
- Voltmeter is placed in parallel with the component.
Constructing Circuits (Multiple setups)
- Parallel Circuit: Build a circuit to demonstrate how a bulb stays lit if one bulb burns out.
-
Series Circuit: Create a battery-lightbulb circuit setup to make the battery last as long as possible.
- Series circuit setup will use less current and therefore increase the battery life.
- Understanding Circuit Types: Compare series circuits to parallel and complex circuits, noting voltage and current behaviors.
- Series circuits share the current in a single path.
- Parallel circuits share the voltage across parallel paths.
Testing Understanding
-
Bulb Brightness Prediction: Determine the order of bulb brightness (from brightest to dimmest) in the given circuits.
- Build the circuits in the simulation to confirm predictions.
- Flashlight Circuit Building: Design a flashlight circuit with two batteries and a light bulb that produces the brightest light.
- Building circuit examples to confirm answers and illustrate reasoning.
