why spark is produced in mosquito bat?and what are the ways
to reduce it?

Answer Posted / ravi pradhan

The net structure is primarily made up of three layers of metal mesh and is rather a complicated assembly.

The inner central layer is actually the "hot" mesh and is terminated as a high voltage source from the circuit enclosed in the lower handle area. The outer two layers are simply connected with the negative of the battery and constitute the ground for a return path to the central “hot” mesh line.

However since the inner layer and the outer layers are separated from each other at a reasonable distance, the high voltage from the central mesh in unable to arc-off through the outer layers, but when a “victim” (a mosquito in this case) flies into this trap and bridges itself in between the layers, its body creates a low resistance path in between the layers of the mesh so that the high voltage is now able to arc through the body of the mosquito which is instantly electrocuted.

The circuit supplying the required high voltages to the above mesh in fact becomes the heart of the whole procedure

The boosted voltage ranging several thousand volts gets stored inside an output AC capacitor across the output HOT ends which are finally terminated to the bat meshes and becomes ready to “shoot.”

The moment a mosquito or any bug comes in contact with the meshes, the stored high voltage in the capacitor discharges violently through the body of the entangled bug creating a big spark and electrocuting it instantly.

hi, in the event earth grounding is not available in a project, is there any other way to make the elcb work? fyi, i have an instant water heater (6.5kw) installed, however if there is grounding in the heating element inside the heater assembly, i will get grounded. thank you in advance to those who will answer my question.
