Observations

1: From the measured values of circuit current and supply voltage calculate the equivalent circuit resistance

R_EQ= Ω

2: Compare the values of equivalent circuit resistance from the previously measured value and the calculated value above

Measured R_EQ= Ω

Calculated R_EQ= Ω

The two values are

3: Add the two measured values of voltage drop U_R1 and U_R2//R3

U_R1V + U_R2//R3V = V

Did the two values sum to equal the supply voltage U_S

4: Add the two measured values of parallel branch currents I_R2 and I_R3

I_R2A + I_R3A = A

Did the two values sum to equal the supply current I_S

5: What would be the result of a short circuit across resistor R₃.

R_EQ= Ω

I_S= A

The equivalent resistance

6: What would be the result of an open circuit in resistor R₃.

R_EQ= Ω

I_S= A

The equivalent resistance
