6) Keep the values of resistors at their initial values, R1=60, R2=20, R3=80, and R4=40 Connect a new resistance to RI in correct way (series or parallel) to balance the bridge, what is the new resistance, and how you connect it (series or parallel? For having a balanced bridge, R =42 1 1_1_1_ R R R R 4 6 4 R =120 So R =122 must be added in parallel
