Question

A) It has a 1000 turns toroid L = 4 (H) inductance with a radius of 1 m. This toroid is designed to energize for a home that needs 10 kW of power during an electrical outage and energizes for 4 minutes. Calculate the current that will pass over the toroid and the magnetic field that will occur in the toroid. µ0 = 4 π 10 -12 (F / m).

B) With a defibrillator device, when the human heart stops, a current of 12 (A) at 25 volts is applied to the body for 3 milliseconds to operate the heart. Find out the electrical power delivered to the body with a defibrillator and how much energy is transferred during this time?
