Browse: Home / Physics / 9 Electronic circuits / 9.A Circuit Elements


9.A.1 Current (I = ΔQ/Δt, sign conventions, units)

9.A.2 Battery, electromotive force, voltage

Batteries are used everywhere, for instance your iPhone, Miley.

“Yeah I know, charge, battery used up, charge, battery used up. The never ending cycle continues,” Miley responds.

9.A.3 Terminal potential, internal resistance of battery

9.A.4 Resistance

Resistance is given by V=IR

9.A.4.a Ohm’s law (I = V/R)

Note Ohm’s law is NOT V=IR. Components that follow Ohm’s law…
