Longer resistance wire means more electron-ion collisions hence greater resistance and reduced current. If connections are made between the two lower terminals it will act as a fixed resistor .

Series-parallel circuit. The Figure at right shows three impedances; two are connected in parallel and then connected in series with a third impedance. Each impedance can be a pure resistance, a pure ...

The x-axis represents the series resistance and the y-axis represents the series reactance. Figure 2: Constant parallel resistance maps as a circle. (Click on image to enlarge) There are two circles ...

Parallel Connection ; Series-Parallel Connection (for more than 2 speakers) There are pros and cons to each method which we will discuss herein. To understand the differences, we must first explore ...

Everything CCEA students need to know about how to conduct an investigation into the resistance of a metallic conductor.
