There are various ways to prove that resistors obey Ohm's law (V=IR). Ohm's law says that voltage across a component is proportional to the current going thr...

resistor generally means a device that obeys Ohm's Law (many devices do not) and has a resistance R. Two (or more) resistors can be connected in series (as in Figure 1), or in parallel (as in Figure 2). Resistors could also be connected in a series/parallel circuit like Figure 3. Resistor circuits will be explored in Experiment ELEC-3 next week.
