Which of the following statements about batteries is FALSE? A battery is a group of galvanic cells connected in series. Lead storage batteries contain lead at the anode and lead coated with lead dioxide at the cathode. Dry cell batteries are used in tape players and portable radios. A fuel cell is a galvanic cell for which the reactants are continuously supplied. The alkaline dry cell battery can last longer than a nickel-cadmium battery.

00:01 Here you're asked to identify which statement is false regarding a battery.
00:05 The first statement says a battery is a group of galvanic cells connected in series.
00:11 This is correct.
00:12 That's what a battery means is multiple things together.
00:17 And in this case, it's multiple galvanic cells.
00:20 The second statement says a lead storage battery contains lead at the anode.
00:25 Oxidation occurs at the anode.
00:26 The lead is oxidized to lead 2+.
00:29 And lead dioxide, or actually lead 4 oxide at the cathode, reduction occurs at the cathode and the lead 4 is reduced to lead 2.
00:40 So that's true.
00:42 Dry cell batteries are used in tape players and portable radios...
