Drawbacks of Combinational circuits: If students have access to calculators that can do complex-number arithmetic, the “complex” approach is actually simpler for series-parallel combination circuits, and it yields richer (more informative) results. Like voltage, height is a quantity measured between two points (the top of the object and ground level). For example, a two-pole breaker at 15 amps on each pole (breaker handle) would supply 240 volts to the appliance on that branch at up to 15 amps, not 30. electric clothes dryers and ranges), to general purpose 15- and 20-ampere-rated circuits.
