The unit of resistance is the Ohm(Ω). (2)One Ohm is defined as that amount of resistance that will limit the current in a conductor to one ampere when the voltage applied to the conductor is one volt. (3)If a circuit contains resistance in series, the total resistance can be calculated by adding all the individual resistance. The formula is RT=R1+R2+R3+…+Rn Where RT is the total resistance, R1 through Rn are the individual resistance. (4) An inductor is an electrical device which can temporarily store electromagic energy in the field. The inductor is a coil of wire that may have an air core of an iron core to increase its inductance. A powered iron core in the shape of a cylinder may be adjusted in and out of the core. An inductor tends to oppose a change in electrical current, it has no resistance to DC current but has an AC resistance to AC frequency and is given by the formula XL=2πfLL, with units of ohms. Inductors are used for filtering AC current. It is electrically opposite to the capacitor. Its value is expressed in Henry (more monly milliHenries). There are two major types of inductors, air core and iron core. (5) Methods for testing ponents are described below. Resistors are normally checked with an ohmmeter (in all probability on one of the resistance ranges of a multimeter). Such an instruments carries its own power supply and the circuit under test must be disconnected from the subunit power supply if the resistor is only partially removed from the circuit (that is, one end disconnected). Zero resistance on an ohmmeter is normally full scale deflection of the pointer and care must be taken not to confuse this reading with “infinite ohms”. With the meter leads connected together, the ohmmeter is first zeroed, using the electrical control provided. This removes lead resistance from the leading and adjust the zero control appropriate to the chosen range. Capacitors may also be checked for ponent resistance by use of an ohmmeter. On connection the meter initially reads low. Then capacitor is functional, the pointer moves to the high resistance end of the scale as the ponent charges. The reading given when the pointer stops moving is the insulation resistance, which is normally high if the capacitor is in good
