Electric Field
The region surrounding a charged object where a force can be exerted on other charged objects.
What is an Electric Field?
The area around a magnet or a current-carrying wire where magnetic forces can be detected.
What is a Magnetic Field?
The type of current flows in only one direction, such as the current from a battery.
What is a Direct Current?
This unit measures electric current.
What is an Ampere?
This unit measures electric potential difference.
What is a Volt?
Materials that allow the flow of electric charge easily and have low electrical resistance.
What is a Conductor?
The regions on a magnet where the magnetic field is strongest, and they are labeled as north and south.
What is Magnetic Poles?
The type of current that reverses its direction periodically, commonly used in household electricity.
What is an Alternating Current?
This unit measures electrical resistance.
What is an Ohm?
the rate at which electrical energy is converted into other forms of energy and is measured in watts.
What is Power?
Materials that don't allow the flow of electric charge easily and have high electrical resistance.
What is an Insulator?
A region within a magnetic material where the magnetic fields of atoms are aligned in the same direction.
What is a Magnetic Domain?
The combined resistance of multiple resistors connected in a circuit.
This device converts mechanical energy into electrical energy through the process of electromagnetic induction.
What is a Generator?
This device is used to introduce a specific amount of resistance into an electric circuit.
What is a Resistor?
The difference in electric potential energy per unit charge between two points in a circuit.
Potential Difference
A device consisting of a coil of wire wrapped around an iron core and produces a magnetic field when an electric current flows through it.
What is an Electromagnet?
The type of circuit that has multiple paths for current flow, and the total resistance decreases as more resistors are added in parallel.
This device converts electrical energy into mechanical energy, often using the interaction between a magnetic field and a current-carrying wire.
What is a Motor?
A phenomenon occurs when a changing magnetic field induces an electric current in a nearby conductor.
What is Electromagnetic Induction?
The electric potential difference or the driving force that pushes electric charge through a circuit.
Voltage
A process that occurs when a changing magnetic field generates an induced current through a loop of wire.
What is Induction?
The type of circuit has a single path for current flow, and the total resistance increases as more resistors are added in series.
What is a Series Circuit?
These devices are used to increase (step-up) or decrease (step-down) the voltage of an alternating current.
What are Transformers?
closest teams choose. rock, paper, scissors.
Rock always wins.
