A 460 W heating unit is designed to operate with an applied potential difference of 120 V (a) By what percentage will its heat output drop if the applied potential difference drops to 110 V? Assume no change in resistance. %(b) If you took the variation of resistance with temperature into account, would the actual drop in heat output be larger or smaller than that calculated in (a)?
