Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the scientific discipline?Electrical measurements are a branch of metrology, the science of measurement
2. What is the transducer functionality?Transducers convert physical properties (temperature, pressure) into measurable electrical signals
3. Why do we need to measure electricity?Measuring electricity helps us make sure lights, computers, and factories work safely and efficiently. It also lets scientists learn new facts about how the world works.
4. How do we measure voltage and current?We use devices called voltmeters to read voltage and ammeters to read current. These tools use magnetic effects or digital displays to show the amounts.

Electrical Impedance: The total opposition to alternating current, combining resistance and reactance.
Electrical Admittance: The reciprocal of electrical impedance, measuring how easily current flows.
Phase: The time difference or shift between two oscillating electrical signals, like current and voltage.
