Series and parallel circuits - OCR 21st Century Parallel circuits Electrical current transfers energy around circuits. There are two different types of circuits – series and parallel.

Figure 3: Series-to-parallel conversion simplifies circuit analysis. (Click on image to enlarge) The output impedance is highest at resonance, so the filter resonance frequency must first be ...

Series and parallel circuits Measuring current and potential difference. ... You can measure the potential difference across a cell or battery. If the two or more cells point in the same direction ...

I have a Sears deep-cycle lead-acid 12v battery already which I've only used once or twice a year for certain power applications. I was thinking of purchasing an identical model and wiring it in ...
