MDCAT Physics QUESTION #372
Question 1
Resistance in RC circuit of time constant 2 seconds is 1000 Ohms. What is value of C in the circuit?
  • 2 ? farad
  • 20 ? farad
  • 200 ? farad✔️
  • 2000 ? farad
Correct Answer Explanation
? = RC, so C = ?/R = 2/1000 = 0.002 F = 2000 ?F. However, answer key shows C, which is 200 ?F
