A characteristic of certain fundamental particles.
charge
What is the variable for “CHARGE”
q
The unit for quantity of charge is
coulomb
What is the Universal Electrostatic Constant
K 9x10^-19
The rate at which electric charge
flows
Current
The unit for flow of charge (current) is
Amp (A)
Electric potential energy per unit of charge;
electric “oomph.”
Voltage
The unit for electric potential difference (voltage) is
volt
A measure of the of obstruction to flow of
electric charge that a body possesses
Resistance
What is resistance measured in?
ohm
In a series circuit, there is/are how many paths for current to flow?
One
In a parallel circuit, there is/are how many paths for current to flow?
more than one
When a balloon is rubbed on a child’s hair, the balloon develops a negative charge. This is because?
A. protons are transferred from the balloon
to the hair
B. protons are transferred from the hair to
the balloon
C. electrons are transferred from the balloon
to the hair
D. electrons are transferred from the
hair to the balloon
D. electrons are transferred from the
hair to the balloon
According to the picture above, what will be the reading on the voltmeter if you add another light bulb in parallel?
It will stay the same
The current through each bulb in series
___________ the total current provided by the
batteries in series.
is equal to
The sum of the potential drops across all of the bulbs in series __________ the total potential
provided by the batteries in series.
is equal to
In the series circuit pictured above, the
______________ is the same throughout the circuit.
current
Materials that allow charges to NOT move
about easily are called
insulators
Materials that allow charges to move
about easily are called
conductors
the study of electrical charges at rest
electrostatics
the study of electrical chargers in motion
electrodynamics
who said 2 opposite types of charges exist (positive & negative)
Benjamin Franklin
the rod TOUCHES the electroscope.
electroscope has SAME CHARGE as rod.
charged by conduction
the rod DOES NOT TOUCH the electroscope.
electroscope has OPPOSITE CHARGE as rod.
charged by induction
