If the voltage impressed across a circuit is held constant while the resistance is halved, what change occur?

The current doubles

Explanation:

In a circuit, Ohm's law gives the relationship between voltage, current and resistance:

where

V is the voltage

R is the resistance

I is the current

In this problem,

V is held constant

R is halved:

Therefore, the new current is

So, the current doubles.

s the environmental science is a broader field that incorporates many elements of earth and life sciences, whereas ecology is usually more focused on how organisms interact with each other and their surroundings, and often on a very specific population of living things. soo yea
