  1. INDUCTANCE CAPACITANCE AND MUTUAL INDUCTANCE Preparedby: Ertuğrul Eriş Referencebook: ElectricCircuits, Nielsson, Riedel Pearson, PrentenceHall,2007 Updated 1 : October 2011

  2. IDEAL INDUCTANCE, CAPACITANCE, AND MUTUAL INDUCTANCE, ELEMENTS (SELF, KAPASİTE, ORTAK ENDÜKTANS ) • Inductance • Inductor (coil, bobin) • Changing current, moving charge • Magnetic field • Stores energy, passive element • Capacitor • Electrical conductors(iletken) are separated by dielectric material (insulating material, yalıtkan) • Changing voltage, separated charge • Electrical field • Stores energy, passive element • Serial, parallel inductances and capacitances • Mutual inductance (Ortak İndüktans ) • Magnetically coupled ınductors Modellingcoilsandcapacitorsby ideal elements Ertuğrul Eriş

  3. IDEAL INDUCTOR(L, self, bobin) Inductance (L) unit:H, henry Derivative of the inductor current with respect to t, Integral of voltage; analog computers Ertuğrul Eriş

  4. TYPICAL INDACTANCE VALUES/DIMENTIONS nH µH MH Ertuğrul Eriş

  5. IDEAL INDUCTOR(L) Short circuit for DC current Current cannot change instantaneously, «Derivative» Voltage may change instantaneously, «Integral» Linear Element Passive Element Ertuğrul Eriş

  6. EXAMPLE: V(t), I(t) VARIABLES FOR AN INDUCTOR What happens when a DC-current source being used? What happens when a AC-current source being used? frequency Ertuğrul Eriş

  7. EXAMPLE: V(t), I(t) VARIABLES FOR AN INDUCTOR What happens when a DC-voltage source being used? What happens when a AC-voltaget source being used? frequency Ertuğrul Eriş

  8. POWER AND ENERGY IN THE INDUCTOR Negative power!! interpretation. Ertuğrul Eriş

  9. IDEAL CAPACITOR C:capacitance, unit: F, farad Derivative of the capacitor voltage with respect to t, Integral of current; analog computers Gerilime göre türev, akıma göre integral alıyor: Analog bilgisayar Ertuğrul Eriş

  10. IDEAL CAPACITOR • Open circuit for DC current • Voltage cannot change instantaneously, «Derivative» • Current may change instantaneously, «Integral» • Linear Element • Passive Element Ertuğrul Eriş

  17. PARALLEL CAPACITORS Equivalent capacitance, Ceq Benefit(s)? Ertuğrul Eriş

  18. MUTUAL INDUCTANCE ELEMENT(M) (Ortak induktans) • Definition relation, v-i relation Ertuğrul Eriş

  19. MUTUAL INDUCTANCE ELEMENT(M) • Polarity of mutually induced voltage depends on the way the coils are wound in the relation to the reference direction of coil currents. • Dot convention • When the reference direction for a current enters to dotted terminal of a coil, the reference polarity of the voltage that it induces in the other coil is positive at its dotted terminal • OR • When the reference direction for a current leaves the dotted terminal of a coil, the reference polarity of the voltage that it induces in the other coil is negative at its dotted terminal Ertuğrul Eriş

  20. MUTUAL INDUCTANCE ELEMENT(M) • Dot convention • When the reference direction for a current enters to dotted terminal of a coil, the reference polarity of the voltage that it induces in the other coil is positive at its dotted terminal Ertuğrul Eriş

  21. EXAMPLE MUTUAL INDUCTOR İg=16-16 e-5t A; İ1=4+64 e-5t -68e-4t A; 12=1-52e-5t+51e-4t A Ertuğrul Eriş
