Question

Consider the circuit shown in the figure below. (Assume R1 = 12.00 ?, R2 = 1.90 ?, and V = 12.00 V.)

(a) Calculate the equivalent resistance of the R1 and 5.00-? resistors connected in parallel.
1
(b) Using the result of part (a), calculate the combined resistance of the R1, 5.00-?, and 4.00-? resistors.
2
(c) Calculate the equivalent resistance of the combined resistance found in part (b) and the parallel 3.00-? resistor.
3
(d) Combine the equivalent resistance found in part (c) with the R2 resistor.
4
(e) Calculate the total current in the circuit.
5
(f) What is the voltage drop across the R2 resistor?
6
(g) Subtracting the result of part (f) from the battery voltage, find the voltage across the 3.00-? resistor.
7
(h) Calculate the current in the 3.00-? resistor.

Explanation / Answer

(f) voltage drop across r2 = R2 * i = 2.963*1.9 = 5.6297 v (g) 12-5.6297 = 6.3703 V (h) 6.3703/3 = 2.1234 A
