Consider the circuit shown in the figure below. (Assume R1 = 12.0 Ω, R2 = 2.70 Ω, and V = 7.95 V.)
4.00 Ω
5.00 Ω
3.00 Ω
a) Calculate the equivalent resistance of the R1 and 5.00 Ω resistors connected in parallel: .2833 Ω
(b) Using the result of part (a), calculate the combined resistance of the R1, 5.00 Ω, and 4.00 Ω resistors: 2.833 Ω
(c) Calculate the equivalent resistance of the combined resistance found in part (b) and the parallel 3.00-Ω resistor: 5.667 Ω
(d) Combine the equivalent resistance found in part (c) with the R2 resistor: 3.266 Ω
(e) Calculate the total current in the circuit: 2.43 A
What is the voltage drop across the R2 resistor? 6.57 V
