need help asap, here is the link for the stimulation: https://phet.colorado.edu/en/simulation/circuit-construction-kit-dc-virtual-lab

5) Keep the value of R2= 2 Q, change the value of R1 to balance the bridge, Name: what is the new value. Construct the following electrical circuit (Wheatstone Bridge), using 6) Keep the values of resistors at their initial values, PhET simulation, or using the following link. R1=60, R2=20, R3=80, and R4=42 https://phet.colorado.edu/en/simulation/circuit-construction-kit- Connect a new resistance to R1 in correct way (series or parallel) to balance dc-virtual-lab the bridge, what is the new resistance, and how you connect it (series or You have to play and enjoy using this simulation to be familiar with, parallel? because we are going to use during this period. Set the value of resistors as follows: R1=62, R2=29, R3=80, and R4=42, the power supply at 10V Also connect ammeter between points A, and B, then 7) Set the values of the resistors as: you will be able to answer the following questions R1=42, R2=129, R3=20, and R4=60 Answer the following questions R 1) Is the bridge balanced? How do you decide?
