How to solve this question
Resistance Dimension
Modified true or false. Write True if the statement is true. If not, write false and change the underlined word/s to make the statement true. Electrical energy is purchased in kilowatts. Most home appliances are connected in series. The unit ampere is equivalent to joule/second.
