    Impedance matching transformer question

    1. It is required to pass a current of between 6.0A and 6.5A through an impedance of (1.6 + 1.2i) ohms. With only a 230V supply available, it is proposed to use a transformer for impedance matching. A transformer is available with a turns ratio of 16:1. A laboratory test showed that with the...

    Undergrad Laplace transform of sin(ωt – Φ)

    Hi, I'm doing some preparation work for an upcoming mathematics module at University and I'm going over some Laplace transform questions. Part of one question asks for the Laplace transform of sin(ωt – Φ) and after looking the transform up I've found the answer to be (ω)cos(Φ) + (s)sin(Φ)...
