General Aim of Ohm’s LAw Simulation
- Verify the Ohm’s law.
- Determination of unknown resistance using Ohm simulator.
- Determination of total resistance of resistances connected in parallel and in series.
Method of Ohm’s LAw Simulation
General method using Ohmic resistance circuits in Ohm's law virtual lab.
Learning Objectives (ILOs)
By the end of Ohm’s law simulation, student will:
Understand the relation between current and voltage in a circuit with Ohmic resistance.
Prepare Ohm's law experiment setup to determine the equivalent resistance when many resistors are connected in series or in parallel.
Theoretical Background / Context
- According to Ohm’s law, potential difference between two points of a resistor is directly proportional to the current flowing through this resistor at constant temperature using an Ohmic meter for resistance measurement.
- The proportionality constant is called resistance.
Ohm's law formula for resistance: V = I R
When a number of resistances are connected on series, the total resistance will be:
But, If they are connected on parallel , their total resistance will be:
Principle of Work
- In Ohm’s law simulation, If we measure the potential difference across the resistor and current passing through it, and plot a graph between them, a straight line passes through the origin is obtained whose slope is related to the resistance of the resistor.
- The same procedure is repeated in Ohm’s law simulation to verify the series and parallel connection formulae for resistors.
“With the onset of the COVID-19 pandemic, we found ourselves in a situation that forced us to act quickly to find the best solution available to provide our students with a quality molecular genetics laboratory experience.”
'' Although there are now several vendors offering virtual reality software for physics labs, there is only one that offers a realistic, I feel like I’m in a real lab, solution: PraxiLabs.''
" PraxiLabs offered my students a chance to actively engage with the material. Instead of watching videos on a topic, they could virtually complete labs and realize the practical applications of class topics. This is a quality alternative to in-person labs."
"Great user experience and impressive interaction, I am very pleased to have tried the simulations and will continue to do so."
