Sometimes it’s necessary to drive a resistive load such as an incandescent bulb or heating element from a DC voltage that’s higher than the nominal load voltage. An example would be driving a 6.3-V, ...
Imagine that you have a voltage source in series with some source resistance feeding power to a variable load. The relationship between load voltage, load current, and cell current can be drawn as ...
