- Introduction to Circuitry Problem Solving:
- A crash course review on electric circuits.
- Concept 1: How are individual resistances related to voltage drops?
- Concept 2: What can we conclude about resistors in series?
- Concept 3: What can we conclude about resistors in parallel?
- Concept 4: How can we determine the brightness of a lightbulb?
- Problem Solving for Resistors and Voltage Drops
The two circuits below are configured as shown. Circuit B includes an additional resistor R3 placed in parallel with R1. Compare the values of VR1 and VR2 in circuit compared to circuit (no change, decrease, increase)?
- Problem Solving for Lightbulb Brightness with Switches
Two identical circuits are shown below, except Circuit A has an open switch and Circuit B has a closed switch. How does each lightbulb ( and ) change in brightness compared to when the switch was open? (same, dimmer, or brighter)
- Problem Solving for Complex Circuit with Missing Values
- Solving for Lightbulbs and Terminal Voltage
The circuit is connected to three identical lightbulbs:
