Design an "Ohm's Calculator" Windows Forms Application as shown below. This application uses a group box with three radio buttons to select a calculation: current, voltage, or resistance. Two labels are used to display prompts what input values must to display the text "Result $=".$ Two text boxes are used for input, and the third text box is used to display the output result. Two combo boxes are used to select corresponding units for inputs. You should add two units for an input value into each combo box $($e$.$g$.$ A$,$ mA$,$ V$,$ kV$,$ Ohm, kOhm$).$ The application also uses three menu strip items as follows:

"Compute" when clicked it will compute and display the result for the selected calculation into the output text box.

"Clear" clears all text boxes and combo boxes, unchecks radio buttons, and clears input labels' prompts.

"Exit" will terminate the program.

When a radio button is checked the texts of input labels will be assigned corresponding prompts $($e$.$g$.$ "Current $=>"$ and "Resistance $=>""$ if Voltage radio button is checked, "Current $=>"$ and "Voltage $=>>"$ if Resistance radio button is checked, etc.$)$ and the two corresponding units must be added into both combo boxes.

It is required to follow naming conventions when naming your controls$/$objects$.$
