Question

1) An inductor of .45 mH that has a 2.6 mA current when connected to a circuit. There is a sinusoidal voltage of 12 V applied across the inductor. a) How much time does it take for this to happen? 2) When resistors are connected in series, the equivalence resistances will be closest to the value of: a) Smallest resistor value b) Middle resistor value c) Largest resistor value 3) An electro-magnetic wave of a moving charge will have an electric field and a magnetic field. In an electric circuit, the capacitor will store: a) magnetic field (0) b) electric field (E) 4) An electro-magnetic wave of a moving charge will have an electric field and a magnetic field. In an electric circuit, the inductor will store: c) magnetic field d) electric field (6) 5) The earth is a huge magnet... in the northern hemisphere which magnetic pole would be located there? a) Northern magnetic pole b) Southern magnetic pole c) Geographic north d) Geographic south

Answer 1

2)Answer is c) because , for series connection equivalent resistance R=R1+R2+R3...

Therefore the largest resistor value would be closest to the equivalent resistance.

3)Answer is option b) because , inductor is the component which stores electric energy in electric field.

4)Answer is option c) because , inductor is the component which stores energy in magnetic field when current flows through the circuit.

5)Answer is option b)southern magnetic pole.Because , a magnetic needles north pole always point towards the geographic north indicating that the geographic north is the magnetic south pole of the earth.
