MAGNETIC FORCE CHARGED PARTICLE
Moving charges create an electric current which generates a magnetic field.
The magnetic force due to a moving charged particles in a uniform magnetic field is
F q vB
This equation ind
Moving charges create an electric current which is defined as the rate of change of
The SI unit of current is the Ampere (A) which is 1 A = 1 C/s. By convention, the
CAPACITANCE - CAPACITORS
Capacitors are electric devices used for saving electric charge (energy) and enable us to
Any capacitor consists of two plates with equal and opposite charges on each one.
The magnitude of char
Electric potential energy is the energy needed to change the spatial configuration of charged
particles from initial to final destinations.
We used to take the energy at infinity is zero, therefore
Electric flux is the drift of the electric field through a certain surface. Mathematically it is
defined as closed integral of the scalar product of electric field and surface area
The enclosed surface is calle
Electric field is the space around the electric charge.
Electric field is represented by lines extending away from positive charge and towards
negative charge. These lines are also called the lines of force.
Electric charge is an intrinsic property of particles, such as electrons and protons.
There are two types of charges: positive and negatives.
Electrons have a negative charge.
Protons have a positive charge.
?Which of the following is true about the electrical circuit in your flashlight .4
.a. Charge moves around the circuit very fast - nearly as fast as the speed of light
.b. The battery supplies the charge (electrons) that moves through the wires
.c. The ba
