hum voltage sentence in Hindi

Examples

1. The H-core is interesting because it performs far more efficiently than conventional noise sensing bobbins using steel core pins, requiring less turns of copper wire to produce the required hum voltage.
2. The lower coil is wound with much thicker wire and far fewer turns onto a unique laminated steel bobbin which imparts ultra high efficiency, thus the hum voltage is the same as the upper coil and cancels hum perfectly.
