MATH’S NOTES

s promised last month, we will continue our discussion of super-capacitors in this issue. As we mentioned, these unique devices can actually replace batteries in some applications and can be recharged many times, but have one important consideration that you must be aware of. The maximum voltage of many of these is only around 2.7 volts. If you need higher voltages, then you have to connect them in series. With “normal” capacitors this is not a problem, shows one way to do this safely and to charge them.
