Its kind of my job to give answers

The total voltage is letter A. In order to learn how to make the power system work, it is important to understand what voltage is. It is through voltage that you will learn just how much power is going through the entire circuit. This will make the voltage easier to control if needed.

There are different voltages that are provided by power companies depending on people’s needs. This may vary from country to country. It is best that you understand the type of voltage that your gadgets have and what the countries offer when you are traveling. This can help avoid potential issues in the long run.

60 V

Each voltage value of the resistors connected in parallel is equal to their total source voltage. V = IR = 4(15) = 60
