The opposition offered by a coil to the flow of alternating current is called (disregard resistance) | Inductive reactance |
when more than two inductors of different inductances are connected in parallel in a circuit, the total inductance is | less than the inductance of the lowest rated inductor. |
Transfer of electrical energy from one circuit to another without the aid of electrical connections | Induction |
An increase in which of the following factors will cause an increase in the inductive reactance of a circuit | Inductance and frequency |
When inductors are connected in series in a circuit, the total inductance is | equal to the sum of the individual inductances. |
The value of the induced voltage/current depends on which basic factors during the process of electromagnetic induction? 1. Number of turns in the conductor coil. 2. Strength of the electromagnet. 3. Speed of rotation of the conductor or magnet. | All |
The primary effect of a coil is its property to oppose any change in current through it. This property is called | Inductance |
Doubling the amount of turns in a coil has what affect on the field strength? | Doubles it |
When the length of the coil doubles but the number of turns of the coil remains the same what affect does this have on the field strength? | Reduces it by half |
What does the electrical equation XL = 2(pie) x f x L refer to? | Inductive reactance |
