Note that with a negative resistance, the voltage and current have opposite signs. The electrical resistance per unit length, area, or volume of a substance is known as resistivity.

Three 1 ohm resistors are connected in parallel. If you plot voltage vs.

## resistance

Its just behavior on the V-I graph, where there is a negative slope, and operating in that region would give you a behavior of negative resistance.

Resistance contrasts with conductance , which is a measure of the ease with which electrical current flows through a substance.

Type classification: Simple Resistive Circuits. Powered by: Power into a load is the voltage accross it times the current thru it. Quiz Test. To understand why these things don't exist naturally, consider the power tranfer.

The standard unit of resistance is the ohm , sometimes written out as a word, and sometimes symbolized by the uppercase Greek letter omega: This rule also holds true for most low-frequency alternating-current AC systems, such as household utility circuits.
