What is Photovoltaic Effect?Photovoltaic Effect DefinitionThe photovoltaic effect is the direct conversion of light energy to electrical energy using semiconductor materials.Semiconductor RoleSemiconductors like silicon are crucial as they facilitate the movement and interaction of electron-hole pairs necessary for electricity generation.Charge Carrier DynamicsThe movement of electrons and holes across the semiconductor junction is essential for establishing an electric field that aids in electr

What is the Meissner Effect ?Meissner Effect DefinitionThe Meissner effect is defined as the expulsion of magnetic fields from a superconductor when it is cooled below its critical temperature.Discovery and ExperimentGerman physicists Walther Meissner and Robert Ochsenfeld discovered the Meissner effect in 1933 through experiments with tin and lead samples.Meissner StateThe Meissner state occurs when a superconductor expels external magnetic fields, creating a state with zero magnetic field insi

What is the Seebeck Effect ?Seebeck Effect DefinitionThe Seebeck effect is defined as the conversion of temperature differences into electric voltage, enabling various practical applications.Temperature to ElectricityThis effect generates electricity when there is a temperature difference across the junctions of two different materials.Key Applications Thermocouples Thermoelectric generators Spin caloritronicsMaterial RequirementsEffective materials for the Seebeck effect include metals with low

What is the thermal effect of electric current?Definition of thermal effect of currentWhen the current passes through the resistance, the current does work and consumes electrical energy, generating heat.Calculation formulaQ=I^2 Rt I - The current passing through A conductor in amperes (A); R -- the resistance of the conductor, in ohms (Ω); t -- the time for the current to pass through the conductor, in seconds (s); Q - The heat generated by the current on the resistance, in joules (J)Apply Inca
