Meggar.<\/p>\n<p>A meggar is an instrument used to measure the insulation resistance of an electric circuit relative to earth and one another. It is a high-voltage, low-current device that applies a test voltage to the insulation of the circuit and measures the current that flows. The insulation resistance is then calculated by dividing the test voltage by the current flow.<\/p>\n<p>A tangent galvanometer is a device used to measure the tangent of the angle between a magnetic field and a current-carrying conductor. It is not used to measure insulation resistance.<\/p>\n<p>A current transformer is a device used to measure the current in a circuit without having to connect directly to the circuit. It does this by using a magnetic field to induce a voltage in a secondary coil. The voltage in the secondary coil is proportional to the current in the primary coil. Current transformers are not used to measure insulation resistance.<\/p>\n<p>None of the above is the correct answer.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;Tangent galvanometer&#8221;
