Question

Require help making calculations on the right side of the table.

B. Measurements and analysis of a circuit with fault #2 Measured Values Calculated Values from postulated fault R2= Rs RBC ohms ohms RBD- . 60 RDC-.252kfL ohms VAC- 3 VEC = 3 11 = 5.2mA L= 9.30 4 kr. ohms BD = ohms use measured value of VAC use measured value of VEC i= amps amps RDC = volts volts volts volts - amps amps 13 amps Show the calculation for "Calculated Values" part of the table in your lab report to get full credit. Include the answers to the following questions: From the measurements what type of fault has occurred? Draw the circuit diagram that depicts the postulated fault. What would the reading look like if the fault were of the other type? Reminder add R 802 to R3 when calculating the currents.

Explanation / Answer

R1= 400 ohms, R2=200 ohms,

R3= 100/3=33.33 ohms apprx

RBC = 400 + 33.33= 433.33 ohms= 0.433 kohms

RBD=600 ohms= 0.6 kohms

RDC= 233.33 = 0.233 k ohms

VAC= 3 volts

VBC= 3 volts

I3= I1 + I2----------eq(1)

3= I1 (400) + I3 (33.3)---------eq(2)

3= 400 I1 + 33.33 I1 + 33.33I2-

3= 433.33 I1 + 33.22 I2 ----------eq(3)

3= 200 (I2) + I3 (33.33) --------eq(4)

3= 233.33 I2 + 33.33 I1 --------eq(5)

solving eq(3) and eq(5),

0 = 400 I1 - 200 I2

I2= 2 I1

3= 233.33 I2 + 33.33 I1

I1= 3/499.99 = 6 mA

I2= 12 mA

I3= 18 mA
