At least 10 Ohm.<\/p>\n<p>A stiff voltage source is a voltage source with a very small internal resistance. This means that the voltage across the source is almost constant, regardless of the current that is drawn from it.<\/p>\n<p>If a load resistance is 1 kW, then the current that is drawn from the source will be 1000 A. If the internal resistance of the source is less than 10 Ohm, then the voltage drop across the source will be more than 100 V. This is a significant voltage drop, and it will cause the voltage across the load to be less than the voltage of the source.<\/p>\n<p>Therefore, the internal resistance of a stiff voltage source must be at least 10 Ohm.<\/p>\n<p>Option B is incorrect because a stiff voltage source has a very small internal resistance.<\/p>\n<p>Option C is incorrect because a stiff voltage source has a very small internal resistance.<\/p>\n<p>Option D is incorrect because a stiff voltage source has a very small internal resistance.<\/p>\n<p>Option E is incorrect because a stiff voltage source has a very small internal resistance.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;At least 10 Ohm&#8221; option2=&#8221;less than 10 Ohm&#8221; option3=&#8221;More than 100 k Ohm&#8221; option4=&#8221;Less than 100 k Ohm E.
