Chapter 3 - Electricity (3.1) Part 1 Flashcards
What is the measurement of electric charge
Coulombs ( C )
What is the charge of 1 electron
-1.6x10^-19
What is the equation for charge?
Number of electrons x Charge of an electron
Definition of current?
The rate of movement of current
When does current occur?
When a charged particle that is free to move experiences an electric force. The particle is accelerated by the force.
What is the formula for current?
Current = charge passing a point / time for charge to pass
What are Ionic charge carriers?
Charged particles that aren’t electrons that can carry electricity ( can move through object like electric current) for example aluminium ions
SI units for 1 Ampere?
1 C/s
What is charge?
The cause of electromagnetic force and the basic aspect to describe electrical effects
Equation for voltage?
Energy transferred / Charge passing point
What is the correct term for the voltage going into a circuit?
Electromotive force (EMF)
What is the correct term for the voltage being transformed into other forms of energy?
Potential difference
What is the amount of energy per 1 electron volt ?
1 eV = 1.6x10^-19 J
Equation for resistance
R = V / I
If a component through which current is proportional to the voltage. What is the component referred to as?
An Ohmic Conductor, because it follows ohms law
