Q1. If V is the electric potential in an electromagnetic field, then find the notation of \(dV\)

\(dV = \frac{\partial V}{\partial x} dz+ \frac{\partial V}{\partial y} dx+ \frac{\partial V}{\partial z} dy\)

\(dV = \frac{\partial V}{\partial x} dx+ \frac{\partial V}{\partial y} dz+ \frac{\partial V}{\partial z} dy\)

\(dV = \frac{\partial V}{\partial x} dy+ \frac{\partial V}{\partial y} dz+ \frac{\partial V}{\partial z} dx\)

\(dV = \frac{\partial V}{\partial x} dx+ \frac{\partial V}{\partial y} dy+ \frac{\partial V}{\partial z} dz\)

\(\frac{8}{16+\omega^2}\)

\(\frac{-8}{16+\omega^2}\)

\(\frac{4}{16+\omega^2}\)

\(\frac{-4}{16+\omega^2}\)

Q3. What is the impulse response of a system with a transfer function \(H(s)\)?

The Fourier transform of the input signal

The Laplace transform of the output signal

The output of the system when the input is an impulse
