(Electrical eng.) For the series circuit shown in Figure, the voltage drop, V2, across resistor R2 and the power, P2, delivered to this resistor are given by the formulas V2 = I R2 and P2 = I V2, where I = E / (R1 + R2). Using these formulas, write, compile, and run a C++ program that prompts users for values of E, R1, and R2 ; calculates the voltage drop and power delivered to R2 ; and displays the results. Check your program by using the test data E = 10 volts, R1 = 100 ohms, and R2 = 200 ohms. After finishing your verification, use your program to complete the following chart:
E (Volts) | R1 (Ohms) | R2 (Ohms) | Voltage Drop (Volts) | Power Delivered (Watts) |
