A series RC circuit has a time constant of 1.0 s. The battery has a voltage of 50 V and the maximum current just after closing the switch is 500 mA. The capacitor is initially uncharged. What is the charge on the capacitor 2.0 s after the switch is closed?
   

   
  a.
  0.43 C
   
  b.
  0 66 C
   
  c.
  0.86 C
   
  d.
  0.99 C

Question 2

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 that the capacitor takes to charge to 63 of its capacity after the switch is closed. What is the current in the circuit at a time interval of seconds after the switch has been closed?
   

   
  a.
  0.14 A
   
  b.
  0.21 A
   
  c.
  0.12 A
   
  d.
  0.32 A
