DC Circuits
1. What is the effect on current when two resistors are connected in series across a battery as opposed to one?
2. What is the subatomic nature of current?
3. How can you find the amount of electrons flowing in a current in a certain time?
4. How do you find resistance based on the shape of a resistor or wire?
5. What can you determine about a circuit from a potential vs. current graph.
6. What is the effect on a string of lights wired in parallel when one burns out?
7. How do you find equivalent resistance of a complex combination of resistors when they are wired in series and parallel in the same circuit?
Please answer the questions and include an explanation for each one. Thank you.
Solution
1) As opposed to a single resistor, when two resistors are connected in series, the equivalent resistance of the circuit increases.
Current is inversely proportional to resistance (I = V/Req), so the current decreases.
