    PENGARUH INTI KOIL TERHADAP TEGANGAN INDUKTOR DAN RESISTOR YANG DIRANGKAI SECARA SERI
    (2013-03-05) Ningsih, Surya; Erwin; Salomo
    The effect of a piece of metal (called Core) such as Fe (Iron), Cu (Copper), and Al (Aluminum) on inductor’s (coils) voltage and resistance has been studied. The coils were designed by varying their turns that is 50,100, and 150 with the length and diameter of 0,05 m and 0,035 m respectively. These coils were then assembled in series with a resistor whose resistance is 150 Ω, and the voltage source as well as switch. The inductor and resistor’s voltage were measured based on applied current. This measurement was carried out for coil without core and coil with a core such as Fe, Al, and Cu. Based on the results of measurements of the inductor’s voltage of coil with Fe core was higher than without a core, however, resistor’s voltage in coil with the addition Fe was smaller than that of a coil without core. Changing the core with Cu resulted smaller inductor’s voltage compared to that of coil without core and the resistor’s voltage is reversed. Inserting of Al as a core into the coil produced higher inductor’s voltage than that of coil without core, and the resistor’s voltage is opposite. This means the coil with large magnetic field generates large inductor’s voltage while resistor’s voltage of the coil was smaller
