Electrical Resistance

Question 0

Variable resistors

Answer 0

When resistance is decreased current will flow through will when it is manually increased, it will restrict the flow of charge

Question 1

Resistance (ohms)

Answer 1

Something that restricts the flow of charge

High resistance converts electrical energy into heat energy

Question 2

Thermistor

Answer 2

When heated, resistance decreases

At room temperature, resistance is large

Question 3

Light dependant resistors

Answer 3

When light intensity is increased, resistance decreases

When light intensity is decrease, resistance increases

Question 4

Diodes

Answer 4

Current can only flow in one direction

High resistance one way low the other way
