The resistance R in ohms of a conductor is given by R- E where E is the potential in volts and I is the current in amperes. Write a script that will: e Call a function to prompt the user for the potential and the current 4. Call a function that will print the resistance; this will call a subfunction to calculate and return the resistance . Write the functions as well. 5. The power in watts is given by P EI. Modify the program in problem 4 to calculate and print both the resistance and the power. Modify the subfunction so that it calculates and returns both values
