Physics Chapter: Electric Charge and Current

A continuous path that allows for the flow of electric current. It consists of a power source, a conductor, and a load.

The opposition to the flow of electric current in a material.

The potential difference across the ends of a conductor is directly proportional to the current flowing through it, as long as temperature remains constant.

The property of a material that determines its resistance to the flow of electric current.

The amount of charge that passes through a conductor per unit time. It's measured in Amperes (A).

The work done to move a unit charge from one point to another in an electric field. It's measured in Volts (V).

The total amount of charge that flows through a conductor. Measured in Coulombs (C).

The energy transferred per unit charge. It's measured in Joules per Coulomb (J/C) or Volts (V).

The rate at which energy is transferred or transformed. It's measured in Watts (W).

The time it takes for a certain amount of charge to flow through a conductor. It's measured in seconds (s).

A fundamental property of matter that causes it to experience a force when placed in an electromagnetic field.

The flow of electric charge through a conductor.

The work done to move a unit positive charge between two points.

The rate at which electrical energy is converted into other forms of energy.

A material that allows electric current to flow easily.

A material with conductivity between that of a conductor and an insulator.

A material that resists the flow of electric current.

The total charge on a body is the sum of all charges on the individual particles within the body.

In a series circuit, the current flowing through each resistor is the same.

In a parallel circuit, the voltage across each resistor is the same.

In a series circuit, the total resistance is the sum of individual resistances.

In a parallel circuit, the reciprocal of the total resistance is the sum of the reciprocals of individual resistances.

The heat generated by an electric current is proportional to the square of the current, the resistance, and the time.

The work done to move a charge through a resistor is equal to the product of the voltage and the charge.

The power input to a circuit is the product of the voltage and the current.

An electric bulb generates light by heating a filament to a high temperature.

A circuit that combines both series and parallel connections of resistors.

A circuit where all components are connected in a single loop.

The energy used by a circuit to allow current flow. It's the product of power and time, measured in watt-hours (Wh).

A low melting point wire in a circuit. It melts if the current rises suddenly, breaking the circuit and preventing damage.

A device that uses a nichrome coil with high resistance to generate heat when current flows.

The heat produced in a resistor is equal to the product of its resistance, the square of the current, and the time for which the current flows.

The amount of energy used when 1 watt of power is consumed for 1 hour. It's the commercial unit of electric energy.

The ability of a material to resist the flow of electric current. It's measured in ohms (Ω).
