Virtual Laboratory of resistance in a wire

This lab uses Resistance in a Wire (https://phet.colorado.edu/sims/html/resistance-in-a-wire/latest/resistance-in-a-wire_en.html) and Circuit Construction Kit: CD of PhET Interactive Simulations at the University of Colorado Boulder, licensed under the CC-BY 4.0 license (https://phet.colorado.edu/sims/html/circuit-construction-kit-dc/latest/circuit-construction-kit- dc_en.html?screens=1)

Build Your Understanding: 1. Open Resistance in a Wire, then explore to develop your own ideas about how the construction of a resistor affects its resistance and the ability to allow current to flow.

Description of experiment 1.

Description experiment 2...

Add more columns if necessary to describe more experiments

Directions: When answering the questions, explain in your own words why your answer makes sense and provide evidence from your experiments #1. Add more experiments to number 1 if you need to get better evidence.

2. If the resistor cross section (area) changes: a. How does it affect the value of the resistor? (Answer, explanation, evidence)

b. How does it affect the current through the circuit? (answer, explanation, evidence)

3. If you change the length of the resistor: a. How does it affect the value of the resistor? (answer, explanation, evidence)

b. How does it affect the current through the circuit? (answer, explanation, evidence)

If you change the resistivity of the resistor, is the effect like changing the length or area? (answer, explanation, evidence)

During manufacturing, how is the resistivity of a resistor changed? Quote your references
