WebAs a result, the resistance is lower in larger cross-section conductors. The number of scattering events encountered by an electron passing through a material is proportional to the length of the conductor. The longer the conductor, therefore, the higher the resistance. Different materials also affect the resistance. Share Cite WebHigh resistance atomizers have an ohm rating of at least 4.2 ohms, and were designed for vaping at high voltages (6 volts and above). Even standard atomizers tend to deiver a burned taste under high electrical current, so manufacturers started upping resistance to cater to high-voltage vapers. Web21 de fev. de 2024 · In the series circuit, the high-resistance load has to dissipate more power than the low-resistance load, so it burns brighter. In the parallel circuit, the power has an easier time getting through the low-resistance load, so it tends to bypass the high-resistance load, leading to less power running through the high-resistance load, … cindy hubbard
