The Power, in Watts, Dissipated as Heat in a Resistor $P = 80 \mathrm { Watts }$

question 5

Multiple Choice

The power, in watts, dissipated as heat in a resistor varies jointly with the resistance, in ohms, and the square of the current, in amperes.A 15-ohm resistor carrying a current of 1 ampere dissipates 15 watts.
How much power is dissipated in a 80-ohm resistor carrying a current of 3 amperes?

• A) \( P = 80 \mathrm { Watts }\)
• B) \(P = 8\) Watts
• C) \(P = 3\) Watts
• D) \(P = 720 \mathrm { Watts }\)
• E) \(P = 24 \mathrm { Watts }\)

Definitions:

Exotic Species

Species that are introduced to a new environment where they do not naturally occur, often leading to environmental changes and potentially becoming invasive species.

Keystone Species

This term refers to a species that plays a critical role in maintaining the structure of an ecological community and whose impact on the ecosystem is disproportionately large relative to its abundance.

Pioneer Species

First organisms to colonize previously disrupted or damaged ecosystems, beginning a chain of ecological succession that ultimately leads to a more biodiverse steady-state ecosystem.

Invasive Species

Non-native species that spread rapidly in a new ecosystem, often causing harm to native species and their habitats.
