Chapter 2: Properties of basic electrical circuits.

Question 1

What instrument do we use to measure current?

Answer 1

Ammeter or fluke.

Question 2

What instrument do we use to measure Voltage?

Answer 2

Voltmeter or fluke.

Question 3

What instrument do we use to measure continuity and insulation resistance?

Answer 3

MIT 420

Question 4

State ohm’s law

Answer 4

Current flowing through a circuit is directly proportional to the applied voltage and inversely proportional to the resistance, provided the temperature remains constant.

I=V/R
