The copper losses are the losses due to the resistance of the windings. The test is conducted by shorting the secondary winding and applying a voltage to the primary winding. The current that flows through the primary winding is then measured. The copper losses are calculated by multiplying the current by the square of the voltage.<\/p>\n<p>The other options are incorrect because:<\/p>\n<ul>\n<li>Hysteresis losses are the losses due to the magnetic hysteresis of the core.<\/li>\n<li>Eddy current losses are the losses due to the eddy currents that are induced in the core.<\/li>\n<li>Core losses are the sum of the hysteresis losses and the eddy current losses.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;hysteresis losses&#8221;
