An ac series circuit has an impedance of 60 Ohm and
Iteru [2.4K]

Answer:

Power factor of the AC series circuit is cos\phi=0.5

Explanation:

It is given that,

Impedance of the AC series circuit, Z = 60 ohms

Resistance of the AC series circuit, R = 30 ohms

We need to find the power factor of the circuit. It is given by :

cos\phi=\dfrac{R}{Z}

cos\phi=\dfrac{30}{60}

cos\phi=\dfrac{1}{2}

cos\phi=0.5

So, the power factor of the ac series circuit is cos\phi=0.5. Hence, this is the required solution.

Based on illustrations of magnetic field lines, where could an object be placed so it would not experience a magnetic force
tiny-mole [99]

<u>Halfway</u><u> between the like poles of two magnets, because the field lines bend away and do not enter this area.</u>

How does a magnetic field diagram show where the field is strongest?

  • The magnetic field lines do not ever cross.
  • The lines include arrowheads to indicate the direction of the force exerted by a magnetic north pole.
  • The closer the lines are to the poles, the stronger the magnetic field (thus the magnetic field from a bar magnet is highest closest to the poles).

Where is magnetic field the strongest and weakest on a magnet?

  • The bar magnet's magnetic field is strongest at its core and weakest between its two poles.
  • The magnetic field lines are densest immediately outside the bar magnet and least dense in the core.

Which two locations on the magnet would have the greatest attractive forces?

  • Inside the magnet itself, the field lines run from the south pole to the north pole.
  • The magnetic field is strongest in areas of greatest density of magnetic field lines, or areas of the greatest magnetic flux density.
