Here is how the virtual laboratory looks like.

Virtual experiment.

Step 1. Change the voltage. How does the current strength change? Make a conclusion. 

Step 2. Change the resistance. How does the current strength change? Make a conclusion.

Conclusion

Current strength is directly proportional to the voltage and inversely proportional to the resistance.
