Question

Which statement correctly expresses the relationship between electric field and electric potential in Cartesian coordinates?

Accepted Answer

Ex=−∂V∂x, Ey=−∂V∂y, Ez=−∂V∂zE_{x}=-\frac{\partial V}{\partial x},	ext{ }E_{y}=-\frac{\partial V}{\partial y},	ext{ }E_{z}=-\frac{\partial V}{\partial z}

Answer

Ex=−∂x∂V, Ey=−∂y∂V, Ez=−∂z∂VE_{x}=-\frac{\partial x}{\partial V},	ext{ }E_{y}=-\frac{\partial y}{\partial V},	ext{ }E_{z}=-\frac{\partial z}{\partial V}

Answer

Ex=−dVdx, Ey=−dVdx, Ez=−dVdxE_{x}=-\frac{dV}{dx},	ext{ }E_{y}=-\frac{dV}{dx},	ext{ }E_{z}=-\frac{dV}{dx}

Answer

Ex=∂V∂x, Ey=∂V∂y, Ez=∂V∂zE_{x}=\frac{\partial V}{\partial x},	ext{ }E_{y}=\frac{\partial V}{\partial y},	ext{ }E_{z}=\frac{\partial V}{\partial z}
