a. A student builds a simple circuit with a single resistor with resistance R and measures an electric potential difference ΔV across the resistor. Then, the student replaces the resistor with a new one of resistance 2R and keeps the electric potential difference the same. What is the current (I2) through the new circuit in terms of the original current​

The new current is half the original current.

Step-by-step explanation:

Ohm's Law:

We use Ohm's law to solve this question. It states that

In which is the voltage difference, R is the resistence, and I is the current.

A student builds a simple circuit with a single resistor with resistance R and measures an electric potential difference ΔV across the resistor.

So

The new current is half the original current.

step-by-step explanation:

the x's and the y's both go up the same amount each time, therefore it will be a linear function because it will go in a straight line when drawn on a graph.

hope this !

answer: i'm not sure
