A 1 000-V battery, a 3 000- resistor and a 0.50-F capacitor are connected in series with a switch. The time constant for such a circuit, designated by the Greek letter, , is defined as the time required to charge the capacitor to 63 of its capacity after the switch is closed. What is the value of for this circuit?
   

   
  a.
  6.0  10⁹ s
   
  b.
  1.7  10¹⁰ s
   
  c.
  1.7  10⁷ s
   
  d.
  1.5  10³ s
