Adding more components to a series circuit increases the total resistance in the circuit, so less current flows. The circuit on the left contains a lamp, a cell, a switch, and an ammeter. 4 A of ...

The resistive elements in the bulbs of the series circuit obey Ohm's Law, which states that the voltage across a resistive element equals the resistance of the element times the current flowing ...

The serious problem with a series circuit is resistance buildup. Every load generates some amount of resistance and heat buildup. But in a series circuit, the total circuit resistance is the sum ...
