Value of current in a short circuit is_

Correct answer: A. Infinite

  • A. Infinite
  • B. zero
  • C. minimum
  • D. maximum

Explanation

Option A is correct since, in a short circuit, there is no resistance to the flow of charges so a large number of charges flow in a very short time. Thus, the current becomes infinite. Option B is incorrect since there is a flow of charges in a short circuit so the current is not zero Option C is incorrect since it states that current will be very less which is not true as current will be large Option D is incorrect as the maximum current can even occur with very low resistance. But when almost zero resistance is provided the current flow becomes infinite.

About Current Electricity

Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
