Question

Consider the circuit shown in the figure below. (Assume -R1 7. 00 Ohm , R2 - 1. 40 Ohm , and V - 9. 00 V. ) Calculate the equivalent resistance of the R1 and 5. 00- Ohm resistors connected in parallel. Ohm Using the result of part (a), calculate the combined resistance of the R1 5. 00- Ohm , and 4. 00- Ohm resistors. Ohm Calculate the equivalent resistance of the combined resistance found in part (b) and the parallel 3. 00- Ohm resistor. Ohm Combine the equivalent resistance found in part (c) with the R2 resistor. Calculate the total current in the circuit. A What is the voltage drop across the R2 resistor? V Subtracting the result of part (f) from the battery voltage, find the voltage across the 3. 00- Ohm resistor. V Calculate the current in the 3. 00- Ohm resistor. A

Explanation / Answer

(a) (7*5)/(7+5) = 35/12 ohm (b) 35/12 + 4 = 6.9167 ohm (c) 6.9167 || 3 = 2.092 ohm (d) 2.092 + 1.40 = 3.492 ohm (e) 9/3.492 = 2.577 ampere (f) 1.4*2.577 = 3.60 V (g) 5.4V (h) 5.4/3 1.8 ampere
