Challenge Problems
Push your limits with challenges.
Question 1
An ideal transformer is designed with a primary voltage of 240V and a secondary voltage of 120V. If the core has an infinite permeability assumption, calculate the expected magnetizing current if a current of 0.1A is flowing.
💡 Hint: Consider what infinite permeability implies about reluctance.
Question 2
Considering Faraday's Law, if the magnetic flux changes by 0.5 Wb in 2 seconds, calculate the induced EMF in a coil with 10 turns.
💡 Hint: Utilize Faraday’s Law for calculating induced voltage given a change in magnetic flux.
