A bstract The frequency domain response of a grounded linear circuit is deduced. The model of the ground is a homogeneous conducting half‐space whose horizontal and vertical conductivities are specified. The source itself is formulated as an insulated current‐carrying wire of finite length lying on the surface that is grounded at its end points. The tangential electric field expressions are used to calculate the induced voltage between two additional electrodes that are connected by an insulated wire. Particular attention is paid to the transient coupling response in the potential circuit when the source current is a step‐function of time. Among other things, it is shown that the voltage response is a step‐function only if the circuits are at right‐angles and if the ground is effectively isotropic and nonpolarizable.
