Question

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 B 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 B d) electric field E 5) The earth is a huge magnet... in the southern 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)When all resistances are in series then there equivalent resistance is equal to the sum of all resistances i.e.-

$R_{eq}=R_1+R_2+R_3+---------$

Let three resistances 1ohm,2 ohm and 3 ohm are in series then their equivalent resistance-

$R_{eq}=1+2+3=6\Omega$

So we can see that 6 ohm(Lagest resistor value) is closest to 3 ohm as compared to other 2 resistors.

So option(c) is correct.

(3) In an electric circuit the capacitor stores energy in the form of electic field between its plates.

So option(b) is correct.

(4) When current flows in inductor then magnetic field creates inside it.Hence an inductor stores energy in the form of its magnetic field.

so option(c) is correct.

(5)Earth behaves as a huge magnet whose northern pole lies in the earth's southern hemisphere and Southern pole lies in the earth's northern hemisphere.

So in the given options,option(a) is correct.
