1. Choose Conventional Current
2. Use the components in the left side to build the circuit shown below: Note* there is a larger resistor in the components menu.
3. Click on the resistor (R₁) and fix it at 1000?. That is R₁ = 1000?.
4. R₂ = 1000? and R₃ = 100?
5. Click on the Battery to the left (e₁) and fix it at 9V, e₁ = 9V.
6. Click on the Battery to the right (e₂) and fix it at 6V, e₂ = 6V
7. Click on the Voltmeter from the right side and drag it to measure (V₁) the voltage across R₁, (V₂) the voltage across R₂ and (V₃) the voltage across R₃.

1. Click on the Ammeter from the right side and drag it and put it in series with R₁ to measure (I₁), with R₂ to measure (I₂) and with R₃ to measure (I₃).

Record the values (I₁, I₂, I₃,V₁, V₂ and V₃ ) into table 1
