3\,\text{mega ohm}

resistor and an uncharged

1\,\mu\text{F}

capacitor are connected in a single loop circuit with a constant source of

4\,\text{volt}

. At one second after the connection is made what are the rates at which energy is being delivered by the source? (A)

16(1-e^{-1/3})\,\mu\text{J/s}

(B)

16\,\mu\text{J/s}

(C)

\frac{16}{3}e^{-1/3}\,\mu\text{J/s}

(D)

\frac{16}{3}(1-e^{-1/3})\,\mu\text{J/s}
