Forced electromagnetic oscillations. Alternating current
Grade 11, section 2, lesson 3. Lesson 2: , . Section 1: 50 Hz AC, . Forced oscillations — the circuit is driven by an external EMF; at matching frequency — resonance.
Grade 11, section 2, lesson 3. Lesson 2: x(t)=Asin(ωt), ω=2πν. Section 1: 50 Hz AC, ν0=1/(2πLC). Forced oscillations — the circuit is driven by an external EMF; at matching frequency — resonance.
