    • @asmakanwal7905
      @asmakanwal7905 ปีที่แล้ว +2

      Of course! In a DC motor, the electricity coming from the battery or power source is always flowing in one direction, which is direct current (DC). Inside the motor, there's a part called the commutator that switches the direction of the current in the motor's coils to keep the motor turning. This reversal of current inside the motor doesn't change the fact that the power coming from the battery is still direct current (DC). So, the motor runs on DC, even though the current inside it changes direction as it operates. It's like a one-way road (DC) with a switch that allows a car to go back and forth (inside the motor) while the road itself remains one-way.

    Sir I have a question..When the coil reaches the exact Vertical postion we assume that it changes its position due to inertia.So sir If the intitial forces were in opposite directions then inertia should be also cancelled out

    • @bebright-4840
      @bebright-4840 ปีที่แล้ว

      Answer?

    • @asmakanwal7905
      @asmakanwal7905 ปีที่แล้ว

      ​@@bebright-4840 Certainly! When the coil in a DC motor reaches the top position and starts to change its direction, it continues to move because of inertia. Inertia is like a "keep going" force, and it resists changes in motion. It doesn't cancel itself out; rather, it helps keep the coil moving. The coil changes direction because of the motor's design and the interaction between its magnetic parts, not because inertia cancels itself.

  • @qarneetechnical7004simple

    Sir the ans is that it will rotates due to inertia. Because everything in motion can't shop immediately if external force is not allied so the coil will rotate by inertia.

    Current direction aur coil location tu after 180° k bad change ho gi, phir coil again move kery gi 90° tk , but 90° to 180° degree tk kesy rotation hoti ha coil may ?

      But due to inertia coil move Krti he
      Phir inertia ki wajah se move krke commutators change hote hen
      Commutators ke lehaz se current ki direction change Ho jati he
      But overall coil me current ki direction same rehti he
      Phir again whi process coil me current flow krta he force apply hoti he
      90 degree pr pohnch kr current stop Force stop or phir inertia ki wajah se move krti he coil

    Flemming's left hand rule is also cause of rotation

    • @asmakanwal7905
      @asmakanwal7905 ปีที่แล้ว +1

      Fleming's Left-Hand Rule is indeed a key concept in understanding the operation of a DC motor. This rule helps determine the direction of force or motion in a current-carrying conductor when placed in a magnetic field. When applied to a DC motor, it helps explain why the motor rotates.
      In Fleming's Left-Hand Rule:
      - The thumb represents the motion or force direction (mechanical motion).
      - The first finger represents the magnetic Field direction.
      - The second finger represents the current direction.
      When a current flows through the coil of a DC motor (represented by the second finger), it creates a magnetic field around the coil. When this coil is placed in the magnetic field of the permanent magnet (represented by the first finger), the thumb (motion) will point in the direction of rotation. This rule illustrates the interaction between the magnetic field created by the current in the coil and the external magnetic field, leading to the motor's rotation.
      So, yes, Fleming's Left-Hand Rule helps explain why DC motors rotate by showing the relationship between current, magnetic field, and the resulting mechanical motion.
