Electrostatics & Charge
This property determines whether two objects attract or repel each other.
What is electric charge?
This quantity describes how much energy each unit of charge carries.
What is electric potential difference (voltage)?
This quantity measures how much charge passes a point each second.
What is electric current?
This property increases when a wire becomes longer.
What is resistance?
In this type of circuit, current is the same everywhere.
What is a series circuit?
When electrons move from one object to another, this type of electricity is produced.
What is static electricity?
Charge naturally moves from this type of potential to the opposite type.
What is high potential to low potential?
Conventional current flows in this direction relative to electron flow.
What is the opposite direction?
Thicker wires have lower resistance because they offer more of this for electrons.
What is cross‑sectional area?
In this type of circuit, each branch receives the same voltage.
What is a parallel circuit?
This law describes how electric force depends on charge size and distance.
What is Coulomb’s Law?
This device must be connected across a component to measure voltage.
What is a voltmeter?
A current of 2 A flowing for 10 seconds moves this much charge.
What is 20 coulombs?
This material property determines how strongly a substance resists current flow.
What is resistivity?
Adding more resistors in parallel does this to total resistance.
What is decreases it?
When a charged object causes charges in another object to rearrange, this process occurs.
What is polarization?
Energy is lost across circuit components because they do this to the charge.
What is convert electrical energy into other forms?
This unit is used to measure current.
What is the ampere?
Raising this physical condition of a metal wire increases its resistance.
What is temperature?
A single break in this type of circuit stops all current.
What is a series circuit?
Doubling the distance between two charges causes the electric force to change by this factor.
What is one‑fourth?
This term describes the energy change per coulomb of charge between two points.
What is potential difference?
A circuit with no complete path will have this amount of current.
What is zero?
The resistance of a wire depends on length, area, and this material‑specific factor.
What is resistivity?
Homes use this wiring type so devices can operate independently.
What is parallel wiring?
