Two coils, held in fixed positions, have a mutual inductance of M = 0.0034 H. The current in the first coil is I(t) = I0sin(ωt),
tiny-mole [99]

Answer:

ε₂ =2.63 V

Explanation:

given,

M = 0.0034 H

I (t) = I₀ sin (ωt)

I (t) = 5.4 sin (143 t)

\dfrac{d i(t)}{dt} = \dfrac{d}{dt}(5.4 sin (143 t))

\dfrac{d i(t)}{dt} =143 \times 5.4 cos (143 t)

magnitude of the induced emf in the second coil

ε₂ =M\dfrac{di}{dt}

ε₂ =0.0034\times 143 \times 5.4 cos (143 t)

for maximum emf

cos (143 t) = 1

ε₂ =0.0034\times 143 \times 5.4

ε₂ =2.63 V

Find the steady-state charge qp(t), and the steady-state current ip(t),in an LRC-series circuit when
Dmitry_Shevchenko [17]

(a) The value of the steady state charge in the circuit is 3 C.

(b) The steady-state current ,in an LRC-series circuit is 5.3 A.

<h3>Steady state charge</h3>

The value of the steady state charge in the circuit is calculated as follows;

Q = CV(max)

Q = 0.1 x 30

Q = 3 C

<h3>Steady state current in circuit</h3>

I = V/R

Vrms = 0.7071 x V(max)

Vrms = 0.7071 x 30

Vrms = 21.21 V

I = Vrms/R

I = 21.21/4

I = 5.3 A
