Electromagnetism – Faraday’s law

The circuit shown is in a uniform magnetic field that is into the page and is decreasing in magnitude at rate of 150 tesla/second. The ammeter reads A. 0.15 A B. 0.35 A C. 0.50 A D. 0.65 A E. 0.80 A (GR9677 #02) Solution: V − IR − ɛ = 0 I = (V − ɛ)/R ɛ = − dΦ/dt = −AdB/dt Given: dB/dt = −150 t/s (minus …
