Electricity and Magnetism

Question 1

What do voltage and current sensors measure?

Answer 1

electricity passing through them

Question 2

What do hall sensors detect? What are their two varieties?

Answer 2

Magnetic field; One detects the presence of magnet and another tells strength of the magnetic field in teslas

Question 3

What is used in Arduino to measure battery pack voltage?

Answer 3

Attopilot

Question 4

What does AttoPilot Compact DC Voltage and Current Sense measure? In what form is it reported?

Answer 4

big voltages and current; analogue

Question 5

What is power (P) a function of?

Answer 5

Voltage (V) and Current (I); P=VI

Question 6

What is the hall effect?

Answer 6

When magnetic field causes electrons to divert from
their straight path, causing a voltage change in a
conductor

Question 7

How does Hall sensor report magnetic field?

Answer 7

as a voltage that can be read like an analog

resistance sensor

Question 8

Example of Hall effect sensors?

Answer 8

“KY-024 Magnetic Detecting Sensor”

Question 9

What sensor gives direction of magnetic north? What is it sensitive to?

Answer 9

LSM303 compass-accelerometer; external interference

Question 10

What sensor gives direction of magnetic north? What is it sensitive to?

Answer 10

LSM303 compass-accelerometer; external interference
