- Ohm’s Law states that the current that flows in a circuit is directly proportional to the voltage across the circuit and inversely proportional to the resistance of the circuit.

- When two ends of an ideal voltage source which delivers an adjustable terminal voltage V, are connected with the connecting wires of a resistor R, the current I flows through the resistor and OHM’s law reads:

- In this experiment, the current flowing through a resistor will be measured as the voltage across the resistor is varied then through the graphical representation the Ohmic resistance will be calculated.

Tens of 3D simulations of science with you everywhere and all the time

You can easily access more than 130 of the 3D simulations of Physics, Chemistry and Biology anytime via your PC, laptop, tablet or even your smartphone, without any need to install an additional driver software.

Our virtual lab aims to facilitate the science teaching process for educators and also make it easy for students to absorb the theory and the application of all science experiments.

All of the 3D simulations are baked with a helping multimedia files to ensure that all learners can perform the science experiments without facing any difficulties.

Our virtual labs enable your institution to save most of physical labs budget

Save most of the money you always dedicate to spend on the materials and tools of the physical science labs. PraxiLabs will enable your students to repeat the steps of the experiments for unlimited times without any need to spend more money to get lab supplies.

Praxilabs will reduce the regular costs that allocated for the maintenance of the equipment of your physical labs as well as helps to increase its lifetime due to the lower frequency of usage.

You will also be able to teach your students how to perform the science experiments that requires a very expensive equipment without the need to purchase such equipment.
