A toroidal solenoid has 2900 closely wound turns, cross-sectional area 0.450 cm², mean radius 9.00 cm, and resistance R = 2.80 Ω. The variation of the magnetic field across the cross section of the solenoid can be neglected. What is the amplitude of the current in the solenoid if it is connected to an ac source that has voltage amplitude 24.0 V and frequency 365 Hz?
