Electric Circuits Flashcards
Ohm’s Law
Ohm’s law states that the potential difference across a conductor is directly proportional to the current in the conductor at constant temperature.
Ohmic Conductors
Ohmic Conductors are conductors that obey Ohm’s Law, where the current is directly proportional to the potential difference.
Non-Ohmic Conductors
Non-Ohmic Conductors are conductors that do not obey Ohm’s Law, where the current is not directly proportional to the potential difference.
Kilowatt Hour (kWh)
Kilowatt Hour (kWh): The unit of electrical energy equal to the use of 1 kilowatt of power for 1 hour.
Internal Resistance
Internal Resistance is the inherent resistance within a source of electrical energy, such as a battery or power supply.
Emf
EMF (electromotive force) is the maximum energy provided by a battery per unit charge passing through it.
Terminal Potential Difference
Terminal potential difference as the voltage measured across the terminals of a battery when charges are flowing in the circuit.
Potential Difference
Potential difference across the ends of a conductor as the energy transferred per unit electric charge flowing through it.
Current Strength
Current strength (I) is the rate of flow of charge. It is measured in ampere (A), which is the same as coulomb per second.
Resistance
Resistance is the ratio of the potential difference across a resistor to the current in the resistor.
Series Circuit
Series Circuit is a circuit configuration where the components are connected in a single path, and the current passing through each component is the same.
Parallel Circuit
Parallel Circuit is a circuit configuration where the components are connected in separate branches, and the potential difference across each component is the same.
