Description

"Exploring the Relationship between Current, Voltage, and Resistance" Ohm's Law PPT Courseware 2

1. The relationship between current and voltage

1. When exploring the relationship between current and voltage, what quantity needs to be controlled unchanged? What is the amount of change?

resistance voltage

2. How to change the voltage value?

(1), using sliding rheostat

(2) Change the power supply voltage

Think: Which method is better?

Discussion: What kind of experimental equipment are used when you want to explore the relationship between current and voltage?

(1) Power supply (2) Switch (3) Fixed value resistor

(4) Sliding rheostat (5) Ammeter (6) Voltmeter (7) Wire

2. The relationship between current and resistance

1. When exploring the relationship between current and resistance, what quantity needs to be controlled unchanged? What is the amount of change?

voltage resistance

2. How to complete the experiment?

Use different fixed-value resistors to do the experiment on the relationship between current and voltage, and then compare the currents with the same voltage and different resistors.

Experimental conclusions are obtained based on experimental data analysis:

Line: When the resistance is constant, the current through the conductor is proportional to the voltage across the conductor.

Column: When the voltage is constant, the current through the conductor is inversely proportional to the resistance of the conductor.
