If you install a 20 mfd capacitor and a 40 mfd capacitor in parallel, you receive a total capacitance of _________.

Explanation:
Capacitors in parallel share the same voltage across them, and their stored charge adds. So the total capacitance is simply the sum of the individual values. 20 mfd plus 40 mfd equals 60 mfd, giving a total of 60 mfd. (If they were in series, the total would be a smaller value, calculated differently.)
