Question

(6)6. Find the equivalent capacitance of the combination of capacitors in the circuit of this figure. ー-12V 5.0 μF 1.0 μF (3)7. Which one of the following statements is correct? A) Earth's geographic north pole is the north pole of Earth's magnetic field. B) Earth's geographic south pole is the south pole of Earth's magnetic field. C) The north pole of a magnet points towards Earth's geographic north pole. D) The north pole of a magnet points towards Earth's geographic south pole. E) None of the above statements is correct.

Answer 1

We know when capacitors are connected in parallel equivalent capacitance is = > e = c_1 + c_2 & when connected in parallel equivalent capacitor, 1/c = 1/c_1 + 1/c_2 c = c_1 c_2/c_1 + c_2 c = 6 times 3/6 + 3 micro F = 18/9 micro F = 2 micro F Equivalent capacitance = 2 micro F. The north pole of a magnet points towards Earths geographic north pole (which is a south pole of Earth�s magnet). Because a bar magnets north pole attracts with another magnets south pole. (Hence geographic north pole).
