Question
![**Understanding Factors Affecting Electrical Resistance**
---
**The resistance of a wire depends on __________.**
**Select all that apply.**
- [ ] the wire’s cross-section area
- [ ] the wire’s length
- [ ] the material from which the wire is made
- [ ] the current in the wire
- [ ] the voltage applied across the wire
---
**Instructions:**
Please select all the factors that contribute to the resistance of a wire. Remember that multiple answers may be correct.
**Options:**
1. **The Wire’s Cross-Section Area:**
- Larger cross-sectional areas tend to have lower resistance because there is more space for the current to flow through.
2. **The Wire’s Length:**
- Longer wires have higher resistance due to the greater distance the current must travel through.
3. **The Material from Which the Wire is Made:**
- Different materials have different intrinsic resistivities. Metals like copper and aluminum are often used due to their low resistivities.
4. **The Current in the Wire:**
- This option examines if the amount of electrical current itself contributes to the resistance experienced by the wire.
5. **The Voltage Applied Across the Wire:**
- This option evaluates whether the applied voltage affects the inherent resistance of the wire.
**Actions:**
- After selecting the appropriate factors, click on the "Submit" button.
- For more information or to see the correct answers, click on "Request Answer".
