An airplane in the earth’s magnetic field can develop a voltage between its wingtips.
Svetradugi [14.3K]

Answer:

emf=0.125\ V

According to the Fleming's Left left hand rule we have higher potential on the right edge of the wing.

Explanation:

Given:

  • velocity of plane, v=250\ m.s^{-1}
  • magnetic field, B=5\times 10^{-5}\ T
  • angle between velocity and magnetic field, \theta=30^{\circ}
  • span of the wing, l=20\ m

We know:

emf=B.l.v\ sin\theta

emf=5\times 10^{-5}\times 20\times 250\times sin30^{\circ}

emf=0.125\ V

According to the Fleming's Left left hand rule we have higher potential on the right edge of the wing.

Give a reason why volmeter is always connected in parallel not in series ​
Sergio [31]

Answer:

A reason why voltmeter is always connected in parallel not in series ​is:

<u>A Voltmeter has very high resistance to ensure that it's connection do not alter flow of current in the circuit. Now if it is connected in series then no current will be there in the circuit due to it's high resistance. Hence it is connected in parallel to the load across which potential difference is to be measured.</u>
