I am helping my niece with homework, she has to simulate the Ohm's law circuit. Basically a simple circuit with LED, resistor, and power source.

she can use any online simulation tool but it has to show the voltage drop across each component and prove that ohms law is being applied

The closest online ohms law tool i can find online is https://circuitdigest.com/calculators/ohms-law-calculator

But the simulartion value does not seem to change in this tool while change the voltage and resistor value. Can anyone point me towards the right tool?
