Abstract

DE ACUERDO CON LA INVENCION, SE DETERMINA LA CONDUCTIVIDAD ELECTRICA DE UN CUERPO DE PRUEBA (1) DE MATERIAL SUPRACONDUCTOR, COLOCANDO ESTE EN EL CAMPO MAGNETICO (5) DE UNA DISPOSICION DE BOBINAS (3), EN EL QUE LA DISPOSICION DE BOBINAS (3) ESTA CONECTADA CON UNA DISPOSICION DE CONDENSADORES (4) EN UN CIRCUITO RESONANTE PARALELO (2). SE MIDEN LA FRECUENCIA DE RESONANCIA Y LA RESISTENCIA DE RESONANCIA DEL CIRCUITO RESONANTE PARALELO (2). LA FRECUENCIA DE RESONANCIA SE AJUSTA DE MODO QUE LA RESISTENCIA DE RESONANCIA ES IGUAL A UN VALOR TEORICO PREFIJABLE, Y LA DETERMINACION DE LA CONDUCTIVIDAD ELECTRICA DEL CUERPO DE PRUEBA (1) TIENE LUGAR MEDIANTE LA MEDICION DE LA FRECUENCIA DE RESONANCIA BAJO LA CONDICION DE QUE LA RESISTENCIA DE RESONANCIA SEA IGUAL AL VALOR TEORICO.
