    Malengo ya kujifunza

    Mwishoni mwa sehemu hiyo, utaweza:

    • Eleza jinsi sasa inatofautiana katika kupinga, capacitor, na inductor wakati katika mfululizo na chanzo cha nguvu cha ac
    • Tumia phasors kuelewa angle ya awamu ya kupinga, capacitor, na inductor ac mzunguko na kuelewa nini angle ya awamu hiyo ina maana
    • Tumia impedance ya mzunguko

    Mzunguko wa ac umeonyeshwa kwenye Kielelezo\(\PageIndex{1}\), kinachoitwa mzunguko wa mfululizo wa RLC, ni mchanganyiko wa mfululizo wa kupinga, capacitor, na inductor iliyounganishwa kwenye chanzo cha ac. Inazalisha emf ya

    \[v(t) = V_0 \sin \omega t.\]

    Kielelezo a inaonyesha mzunguko na chanzo cha voltage AC kilichounganishwa na kupinga, capacitor na inductor katika mfululizo. Kielelezo b inaonyesha mawimbi sine ya AC voltage na sasa kwenye grafu hiyo. Voltage ina amplitude kubwa zaidi kuliko sasa na thamani yake ya juu ni alama V0 kwenye mhimili y. Thamani ya juu ya sasa ni alama I0. Curves mbili zina wavelength sawa lakini ziko nje ya awamu. Curve voltage ni kinachoitwa V mabano t mabano sawa na V0 sine omega t. curve sasa ni kinachoitwa I mabano kwa mabano sawa na I0 sine mabano omega t bala phi mabano.
