How can resistance be useful and where can they be useful?

- - Resistance can be useful among the population of a repressive government.

Although it can be dangerous for those who resist, it can also exert pressure

against the regime to alter its repressive practices.

- - Resistance can also be useful in electronic circuits. "Lumped" components with

known numerical values of resistance are used to divide voltage, limit current, and

dissipate controlled amounts of electrical energy.
