Explanation:
First of all get the input from the user, number of rows and number of columns where rows represents seat digit number and column represents the seat letter
rows is initialized to 1 to ensure that row starts at 1 or you can remove it then seat number will start from 0.
The first loop is used for digits starting from 1 to number of rows
The second loop is used for letters starting from 1 to number of columns
since rows and cols are not of the same type that's why we are converting the int type to string type
print(str(rows)+cols) counter will keep updating the columns A, B, C.....
rows= rows + 1 counter will keep updating the rows 1, 2, 3....
Code:
Please refer to the attached image.
Output:
Please enter the number of rows: 2
Please enter the number of columns: 3
1A
1B
1C
2A
2B
2C
Answer:
a.) -147V
b.) -120V
c.) 51V
Explanation:
a.) Equation for potential difference is the integral of the electrical field from a to b for the voltage V_ba = V(b)-V(a).
b.) The problem becomes easier to solve if you draw out the circuit. Since potential at Q is 0, then Q is at ground. So voltage across V_MQ is the same as potential at V_M.
c.) Same process as part b. Draw out the circuit and you'll see that the potential a point V_N is the same as the voltage across V_NP added with the 2V from the other box.
Honestly, these things take practice to get used to. It's really hard to explain this.
