Early RCA Horizontal Circuitry...Help!

[Kevin Kuehn]

By voltage division, I mean how the various electrical and electronic components react to both AC and DC current, and how voltage influences current flow. A starting point is to understand how to calculate DC voltage drops across both series and parallel resistances. Once you can do that you can at least follow how the power supplies divide voltage and distribute power to the various circuits.

Do you mean the additive effect of resistors in series vs the overall resistance in a parallel circuit being a value between the hi and low resistor values? I think I understand that however getting parallel resistance right when you're trying to get a resistance value for a resistor you don't have is a bit harder. I use the online calculators and an educated guess then go by some trial and error to get close enough. Is this what you mean Kevin?

Yes but also how the voltage across, and current through, is calculated. But you have the first part.
