The value of a high resistance is measured by loss of charge method. A capacitor having a capacitance of 2.5μF is charged to a potential of 500V D.C. and is discharged through the high resistance. An electrostatic voltmeter, kept across the high resistance, reads the voltage as 300V at the end of 60 seconds.Calculate the value of high resistance:
  • a)
    469.8MΩ
  • b)
    46.98MΩ
  • c)
    46.8MΩ
  • d)
    4.698MΩ
Correct answer is option 'B'. Can you explain this answer?
