Consider the circuit shown in Figure P18.8. (a) Calculate the equivalent resistance of the 10.0- and 5.00- resistors connected in parallel. (b) Using the result of part (a), calculate the combined resistance of the 10.0- , 5.00- , and 4.00- resistors. (c) Calculate the equivalent resistance of the combined resistance found in part (b) and the parallel 3.00- resistor. (d) Combine the equivalent resistance found in part (c) with the 2.00- resistor. (e) Calculate the total current in the circuit. (f) What is the voltage drop across the 2.00- resistor (g) Subtracting the result of part (f) from the battery voltage, find the voltage across the 3.00-V resistor. (h) Calculate the current in the 3.00-V resistor.
