Electrostatics Basics
The units of electrostatic force.
What is N?
The units of the E field
What is N/C?
The units of the Electric Potential
What is J/C?
Ohm's Law
What is V = IR
What is Amps?
The units of electric potential energy.
What is J?
The type of charge if the field lines point inward.
What is negative?
The difference between electric potential and electric potential energy.
What is that electric potential energy only exists between two particles.
Definition of current.
What is the amount of charge that passes a point per second.
or
dQ/dt
Units for resistance and voltage.
What is ohms and volts?
The charges of these fundamental particles are equal but opposite.
What is the proton and the electron?
What is -k N/C?
The electric potential at a point 3 m away from a 2 C charge and 2 m away from a -1 C charge. (can be given in terms of k)
what is 2k/3 + -k/2 = k/6 J/C
Current in circuit 0.
What is 5/40 amps?
Total resistance of circuit 2
What is 8 ohms?
The reason most objects don't feel an electrostatic force on them.
What is they are neutral (no net charge)?
The field lines give the direction of the force for this.
The potential energy of a system becomes greater when particles of these types are brought close to one another.
What are particles with the same charge?
Current coming out of the battery in circuit 1?
What is 1/3 amp?
Current running through R1 in circuit 2?
What is 2 A?
A particle with a charge of 4 C is placed 3 meters away from a particle with a charge of -3 C. This is the magnitude and direction of force between them. (answer can be given in terms of k)
What is -4k/3 and attractive?
Draw the field lines for a -500 C charge a 700 C placed near one another.
Drawing
Electrons placed in an area with an electric potential will move in this direction.
The total resistance in circuit 3.
What is 2300 ohms?
Power dissipated in R1. Units must be given
What is 10 W?
