Transcribed Image Text:Procedure:
The simplest crcuit is a voltage source (i.e. battery) and resistor. The voltage "pushes' the current.
through the circuit. The resistor turns some of the current into heat (or light), and thus, the voltage
across a resistor drops. This is called Ohm's Law: V RI.

Circuits can contain several resistors. In circuit analysis, it is convenient to reduce all resistors to
one equivalent resistance. Two possible arrangements are called series, and parallel. The diagrams
below show these arrangements, the corresponding equivalent resistances, and the main conclusions
of each arrangement.
