Electricity And Magnetism Flashcards
What charge does a proton have?
Positive
What charge does an electron have?
Negative
What charge does an neutron have?
None
What do Protons attract to?
Electrons
What do Electrons repel to?
Electrons
What are atoms made of?
Protons, Electrons and Neutrons
What is current?
The amount of charge flowing per second.
How is current measured?
Using an Ammeter.
Define series circuit.
A series circuit is one where all the components are all in a single loop.
Define parallel circuit.
A circuit with more than one path of current flow is a parallel circuit. The total voltage is equal to the voltage of any parallel resistance. The total current is equal to the sum of the current of each parallel component.
What is potential difference?
the difference of electrical potential between two points.
How is potential difference measured?
Measured in volts using an voltmeter.
How can you make an electromagnet stronger?
You can make an electromagnet in 3 ways, 1. By making more coils, 2. By using a stronger current and 3. If using a nail, using a more suitable material.
