when electron (charges) move in a parallel direction

What is Electric Current?

the rate at which electrons flow past a given point

the rate at which protons flow past a given point

the rate at which neutrons flow past a given point

potential difference between tow points measured in volts push behind the current.

the opposition presented by a material or device to a current

The difference in electrical potential energy between two places in a circuit.

the opposition presented by a material or device to a current

potential difference between tow points measured in volts push behind the current.

The difference in electrical potential energy between two places in a circuit.

Voltage=resistance (OHMS) x current (Amps)

Resistance (OHMS)= Voltage x current (Amps)

Current (Amps) = Voltage x Resistance (Ohms)

energy source, insulation, friction

What is a simple circuit?

wire, power source, and only one load

a circuit in which the parts are joined one after another such that the current in each part is the same-one path to follow through all loads

a circuit in which there are multiple pathways for current, each load has its own path to and from the battery

What is a series circuit?

a circuit in which the parts are joined one after another such that the current in each part is the same-one path to follow through all loads

wire, power source, and only one load

a circuit in which there are multiple pathways for current, each load has its own path to and from the battery

What is a Parallel circuit?

a circuit in which there are multiple pathways for current, each load has its own path to and from the battery

a circuit in which the parts are joined one after another such that the current in each part is the same - one path to follow through all loads

wire, power source, and only one load

What is a permanent magnet?

retain strong magnetic qualities and are hard to re-magnetize

only possess magnetic qualities while in the field of another magnetic field

a temporary magnetic created by the flow of electrons along a circuit

What is a temporary magnet?

only possess magnetic qualities while in the field of another magnetic field

retain strong magnetic qualities and are hard to re-magnetize

a temporary magnetic created by the flow of electrons along a circuit

What is an electromagnet?

a temporary magnetic created by the flow of electrons along a circuit

only possess magnetic qualities while in the field of another magnetic field

retain strong magnetic qualities are hard to re-magnetize

Example of a permanent magnet?

soft iron such as nails, paperclips

Example of a temporary magnet?

soft iron such as nails, paperclips

a coil of wire attached to a battery that creates a weak magnetic field around the current

a coil of wire attached to a battery and then wrapped around an iron core

What is an electromagnet?

a coil of wire attached to a battery and then wrapped around an iron core

a coil of wire attached to a battery that creates a weak magnetic field around the current

3 ways to increase the strength of an electro magnet?

increasing the number of coils in the wire, increasing the voltage in the circuit by adding more batteries, increase the size of the iron core

decreasing the number of coils in the wire, decreasing the voltage in the circuit by adding more batteries, decrease the size of the iron core

keep the same number of coils in the wire, keep the same voltage in the circuit by adding more batteries, keep the size of the iron core
