WebMay 15, 2016 · Power is the product of voltage and current and is the work done in moving a quantity of charge through a resistance. For example, If a 1 volt difference exists across a 1 ohm resistor, then the charge which will flow through that resistance will be one coulomb per second, (one ampere) and the power dissipated by the resistor will be be 1 watt. WebApr 6, 2016 · More the power, more the heat generated. P ( Power) = V ⋅ I H ( in joules) ∝ V ⋅ I ⋅ t ( in s) ∴ H ( in joules) ∝ P ⋅ t ( in s) The 11.1 volt gloves does not give greater heat just because it has more Potential difference, but because Power is greater in it.
