- 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:
