shared deck Flashcards
Two plastic rods are rubbed together and brought together. They attract each other. This is because:
One is negatively charged, the other is positively charge
When two objects are rubbed together and become charged, what moves between them?
What charge do electrons have?
What is the unit for measuring electric current?
An ampere (A)
Electric current is a flow of:
What are the moving charges in metal conductors?
A 6 V battery is joined to a lamp. The current is 2 A. What is the resistance of the lamp?
What happens to the resistance of a thermistor as the temperature rises?
The resistance decreases at higher temperatures.
What happens to the resistance of an LDR (light dependent resistor) as the light level increases?
The resistance decreases at higher light levels.
