WebStudents should be taught about: •electric current, measured in amperes, in circuits, series and parallel circuits, currents add where branches meet and current as flow of charge •potential difference, measured in volts, battery and bulb ratings; resistance, measured in ohms, as the ratio of potential difference (p.d.) to current •differences in … WebAnswering C suggests a misconception about the relationship between current and potential difference. Remember that increasing potential difference increases the current, so that more energy is transferred to the bulb, so it looks brighter. Answering A or B suggests a confusion with the definitions of these key terms.
WebFeb 17, 2024 · Physics equation help! potential difference = current x resistance? A 10 I'm finding that a few of my resources display this equation differently. My revision books and some BBC bitesize pages say potential difference = (current)^2 x resistance, but others say that you don't need to square the current? Anyone know which one is correct?
