    Engineering Laplace transform of the given circuit

    from mesh analysis,is this formula corect? Equation 1: I1 RE + (I1-I2) R2 - Vs = 0 I1 (R1+R2) - I2 R2 = Vs 4 = I1 (R1+R2) - I2 R2 4 = I1 (10+R2) - I2 R2 I1 = (4 + 10 I2)/40 Equation 2: -I1 R2 + I2 (R2+R3) + Ldi2/dt = 0 put equation 1 to 2 -10 I1 + I2 (10+20) + 0,1 di2/dt=0 -((4 + 10 I2)/40) +...
