Electricity and Magnetism Test Flashcards
- How does electric charge flow?
From high voltage to low voltage
study guide
- What does charge exert when acting at a distance
electric field
notes
- Charging by an electric field is called what?
induction
notes
- list two differences between series circuits and parallel circuits
series has one pathway and it all works at once but in a parallel circuit there are three math ways and the circuit is complex.
notes
- what is a real life example of a series circuit and parallel circuit
series is a flashlight and parallel is a house
study guide
- explain the two ways we discussed to keep a house from overheating
fuse- a piece of metal that melts when overheating and a
circuit breaker- piece of metal that bends when overheating
study guide
- describe what an electromagnet is and list the two ways to increase its strength
an electromagnet is a temporary magnet and u can increase strength by making more loops and making the magnet stronger
An example of a good insulator for an experiment
plastic plate
notes
What is it when non,angelic materials become attracted to magnets
ferromagnetism
In a closed circuit containing one resistor and a battery, if the voltage in the battery increases, the current going through the resistor increases. Why does this occur?
As the electrons are pushed more by the battery, they move faster through the circuit.
A material through which electrons do NOT flow easily is a(n) _______. *
insulator
Circuit that has more than one pathway for current to travel through
Parallel circuit
Providing a path that allows electric charges to travel directly into the Earth rather than traveling through a building.
Grounding
Which of the following objects would NOT be a good insulator of electric charge?
skin
The function of a generator is to change _______. *
0/1
mechanical energy to electrical energy
