A robot is powered with a 9.6V battery with a 2400 mA-hr rating for 10 minutes. We want to replace the battery with a capacitor that can be charged to 20V. The minimum capacitance that works equals ____(xx.x) F.

Fill in the blank(s) with the appropriate word(s).


The robot uses 2.4 A-hr/0.5 hr = 4.8 A on average. With ?t in seconds, C = (?t x I)/ ?V = (10 x 60 x 4.8)/(20 -9.6) = 57.7 F
