Ohm's Law: The current through a conductor between two points is directly proportional to the potential difference or voltage across the two points, and inversely proportional to the resistance between them.

\$I=frac{V}{R}\$

where V is the potential difference measured across the resistance in units of volts; I is the current through the resistance in units of amperes and R is the resistance of the conductor in units of ohms (?).

The following applet is a simulation for AC and DC circuit.
You can click the resistor to add it to the circuit or remove it from the circuit.
The same is true for batterys for DC circuit.

• Please feel free to post your ideas about how to use the simulation for better teaching and learning.
• Post questions to be asked to help students to think, to explore.
• Upload worksheets as attached files to share with more users.
Let's work together. We can help more users understand physics conceptually and enjoy the fun of learning physics!  #### juana17

Ohm's law applies to electrical circuits it states that the current through a conductor between two points is directly proportional to the potential difference or voltage across the two points, and inversely proportional to the resistance between them.

I just remember this topic since my high school day. Thanks for the information.
