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 total resistance (\(R_{T}\)) for this circuit is \(R_{1} + R_{2}\). In a parallel circuit, the net resistance decreases as more components are added, because there are more paths for the ...

Save guides, add subjects and pick up where you left off with your BBC account. Variable resistors have many practical applications including volume controls, eg on a radio, and speed controls, eg ...

However, this is a great time to look at the difference between series and parallel circuits. A Simple Circuit ... Suppose each lightbulb has a resistance R (it doesn't matter than lightbulbs ...

Last month's column covered the behavior of electrical components connected in series and demonstrated ... A common example of parallel resonance is a tuning circuit, as shown in the Figure above. In ...
