A current of $$- 8 + 6\sqrt 2 \left( {\sin \,\omega t + {{30}^0}} \right)\,\,A$$ is passed though three meters. They are a center zero $$PMMC$$ meter, true $$r.m.s$$ meter and moving $${\rm I}$$ron instrument. The respective reading (in $$A$$) will be
A
$$8, 6, 10$$
B
$$8, 6, 8$$
C
$$-8, 10, 10$$

A $$1000$$ $$V$$ $$DC$$ supply has two $$1-core$$ cables as its positive and negative leads: their insulation resistances to earth are $$4\,\,M\Omega$$ and $$6\,\,M\Omega$$, respectively, as shown in figure. A voltmeter with resistance $$50\,\,k\Omega$$ is used to measure the insulation of the cable. When connected between the positive core and earth, the voltmeter reads A
$$8$$ $$V$$
B
$$16$$ $$V$$
C
$$24$$ $$V$$
D
