ELECTROSTATICS
True or False: Protons move from object to object during normal charging processes.
What is False?
Rubbing a balloon on your hair transfers charge by this method.
What is friction (triboelectric charging)?
The unit of electric charge.
What is the coulomb?
The rate at which charge flows.
What is current?
In this type of circuit, current has only one path to follow.
What is a series circuit?
An object with more electrons than protons has this type of charge.
What is negative?
During friction charging, which particle is transferred?
What is the electron?
If the distance between two charges doubles, the force changes by this factor.
What is one-fourth?
Voltage is also called this.
What is electric potential difference?
In this type of circuit, devices are connected on separate branches.
What is a parallel circuit?
What happens when a positive charge is brought near another positive charge?
What is repulsion?
Charging by direct contact.
What is conduction?
Electric field lines begin on this type of charge.
What is a positive charge?
The opposition to current flow.
What is resistance?
Adding bulbs in series causes this quantity to increase.
What is total resistance?
A material in which charge can move freely.
What is a conductor?
Charging without touching.
What is induction?
A battery's positive terminal is connected to one end of a wire and its negative terminal to the other. The electric field inside the wire points from the _____ terminal to the _____ terminal.
What is positive to negative?
The equation relating voltage, current, and resistance.
What is Ohm's Law?
V = IR
If one bulb burns out and all others go out too, the circuit is this type.
What is series?
A neutral object can be attracted to a charged object because of this rearrangement of charge.
What is polarization?
A student rubs Material X and Material Y together. Afterward, X is positively charged and Y is negatively charged. What can be concluded about the electron affinities of X and Y?
What is Y has a greater electron affinity than X?
Electric field strength is greatest where field lines are this.
What is closest together?
Which wire would have the greatest resistance: a short thick wire, a short thin wire, a long thick wire, or a long thin wire?
What is a long thin wire?
Adding branches in parallel causes this quantity to decrease.
What is equivalent resistance?
