Question

(a) Calculate the equivalent resistance ofthe R1 and5.00 resistors connected in parallel.


(b) Using the result of part (a), calculate the combined resistanceof the R1, 5.00 , and4.00 resistors.


(c) Calculate the equivalent resistance of the combined resistancefound in part (b) and the parallel3.00 resistor.


(d) Combine the equivalent resistance found in part (c) withthe R2 resistor.


(e) Calculate the total current in the circuit.
A

(f) What is the voltage drop acrossthe R2 resistor?
V

(g) Subtracting the result of part (f) from the battery voltage,find the voltage across the 3.00 resistor.
V

(h) Calculate the current in the3.00 resistor.
A

Explanation / Answer

a) 1/9 + 1/5 = 3.21 b)3.21 + 4 = 7.21 c) 1/7.21 + 1/3 = 2.12 d) 2.12 + 1.2 = 3.32 e) I = V/R = 10V/3.32 = 3.012A f) V = IR = 3.012A * 1.2 = 3.6144V g) 10V - 3.6144V = 6.3856 h) I = V/R = 6.3856V/3 = 2.129A Hope that helps
