Gold signifies that the tolerance is 15%, so the real resistance could lie anywhere between 4,465 and 4,935 ohms.
Answer 4 & 5 please! thank you!

R values =
Resistor value, R1 = 990 Ohms
Resistor value, R2 = 2050 Ohms

4. Connect the 2nd resistor in parallel with the 1st resistor and connect that combination to the battery.

         Measure the following:

              The current passing through the R1, I1 = ___0.0058____ A

              The current passing through the R2, I2 = ___0.0031____ A

              The current supplied by the battery, I = ___0.0092____ A

             Calculate I1 + I2 =                   A

                    Is the following statement true? I = I1 + I2 Y or N   

             Calculate the energy delivered by the battery

                                                     = V I = ____________ x ____________

                         = ___________ Watts

            

Why is the power delivered by the battery greater than in Step 1?  

Answer: __________________________________________________

  __________________________________________________________

  __________________________________________________________

5. Disconnect the battery from the circuit (but leave the two resistors connected in parallel).  

Use the Multimeter to measure the combined resistance of the two resistors connected in parallel:

           Measure the equivalent resistance, R = ___680___ Ohms

           Calculate 1/R, which equals to:

                                          1/R = 1/R1 + 1/R2 = 1/( ) + 1/ ( )

                                                          = __________ + __________

                                                         = ____________

           Calculate R = ____________ Ohms

Is the calculated R and measured R approximately equal to each other?

Answer 1

14) I t I ₂ = 0.0058 A +0.0031 A -0.0089 A I= 0.0012 A I = I + I Yes, it is true, Power delivered by battery = VxI 640.0092 0.0552 Watts Ballery deleinees more power in this Cose as compared with stehe, because Reg is and Power = V)? least in parallel arrangement Req pal Rear 1 + 1 22 R.
