Included Quiz Questions
A circuit splits into 2 parallel branches. Branch A has two resistors, while branch B has only 1 resistor. If these resistors are all identical, how does the voltage drop across the 2 branches compare?
- It is the same for both
- It is twice as much for channel A
- It is twice as much for channel B
- It is four times as much for channel A
- It is 4 times as much for channel B
Two resistors A and B are in series with each other and connected to a battery. If resistor A is twice the resistance of resistor B, how does the current passing through each resistor compare?
- It is the same for both
- It is twice as much for resistor A
- It is twice as much for resistor B
- It is 4 times as much for resistor A
- It is 4 times as much for resistor B
A voltmeter is connected to either side of a 5 kΩ resistor. The voltmeter reads 10 Volts. How much current is running through this resistor?
- 2 mA
- 5 mA
- 10 mA
- 50 mA
- 20 mA
There are 2 resistors in parallel. The resistance of one of the resistors is much greater than the other. Which of the following is true about the equivalent resistance?
- It is approximately equal to the resistance of the smaller resistor
- It is approximately equal to the resistance of the larger resistor
- It is approximately 0
- It is approximately equal to twice the resistance of the smaller resistor
- It is approximately equal to the sum of the resistance of the 2 resistors

Professor Jared is clearly a genius. Thanks for explaining so well and giving so many detailed examples for helps ur retain the information better. I thought I was lost because I've always struggled in physics, but so happy now seeing my small progress. thank you
