TDC 311. Basic Electronic Circuits. Voltage. A battery / generator has + and - posts. Electrons flow through a circuit from the - post to the + post. The potential difference between the two posts is V, voltage. V is the push of electrons.
Basic Electronic Circuits
Base P blocks flow from emitter to collector.
Need to add a wire from base so electrons have some place to flow.
