Which configuration can lead to maximum voltage in an antenna?

The placement of an inductance in series with an antenna is a configuration that can lead to maximum voltage. This is primarily due to the resonant characteristics of inductors and antennas. When an inductor is placed in series with an antenna, it can help to create a resonant circuit, where the reactive components (inductance and capacitance) are balanced at a particular frequency.

At resonance, the impedance is minimized (or perfectly matched), allowing for maximum voltage across the antenna elements. This is essential in radio frequency applications where the goal is to maximize the efficiency of power transfer from the transmission line to the antenna. In this scenario, the inductance can work to increase the voltage across the antenna by ensuring that it's resonating at an optimal frequency, thus enhancing radiation efficiency.

The other configurations might not yield the same result in terms of maximizing voltage. For example, placing a capacitance in series would typically reduce voltage, while placing it in parallel could create a reactive load that doesn't contribute effectively to voltage increase. Similarly, placing an inductance in parallel can divert current away, which does not facilitate maximum voltage across the antenna.
