Parallel Circuit
Parallel Circuit
An electrical circuit where components are connected in separate branches. If one branch is broken or disconnected, current can still flow through the other branches.
Series Circuit
Series Circuit
An electrical circuit where components are connected end-to-end, in a single pathway. If one component breaks, current stops flowing entirely.

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.
