How Resistance Changes in Circuit Paths

Series and parallel resistor connections change how current and voltage behave in a circuit. This experiment shows how to find the total, or effective, resistance for each setup. It also uses Ohm’s law to relate voltage and current when the resistance is known.

In a series circuit, resistors are ...

Simple circuits such as resistive elements connected in series or parallel are key components of complex electrical circuits.

Connecting resistors in series results in a division of voltage, while sharing the same current.

Conversely, when resistors are connected in parallel, it results in a division of current and the voltage across...
