C. 11.0%
D. 0.110%
Problem 3: Mega 800. A circuit contains a 1μF capacitor, an 8V emf source, and a 100 ? resistor connected in series. If the resistor was replaced with 10 ?, which of the following would happen?

III. The power dissipated by the resistor approaches its maximum value more quickly.
A. II only
B. I and III only
C. II and III only
D. I, II and III
