Answer to Problem 1RQ
ET = 264.47 V | E1 = 149.87 V | E2 = 114.79 V | E3 = 143.48 V | E4 = 120.98 V |
IT = 0.6 A | I1 = 0.3186 A | I2 = 0.3186 A | I3 = 0.2813 A | I4 = 0.2813 A |
RT = 440.79 Ω | R1 = 470 Ω | R2 = 360 Ω | R3 = 150 Ω | R4 = 250Ω |
Explanation of Solution
The circuit diagram is redrawn with given data;
Description:
For the given combination circuit, total resistance will be series combination of R1 and R2 in parallel combination with series combination of R3 and R4. Calculations are shown below,
Using the current IT and resistance RT, we calculate the voltage ET
The individual voltage drops can be calculated using the voltage divider rule.
Since R1 and R2 are series connected, the same current flows through them. Hence, I1=I2
Similarly, R3 and R4 are series connected, therefore I3=I4
Conclusion:
The unknown values have been calculated using rules for combination circuit and ohm’s law.
