Mastering these questions does more than help you pass a test. It teaches you why your phone charges slower with a weak cable (resistance), why house lights are wired in parallel (so they don't all turn off), and why fuses are important (prevent over-current).

acts as the energy source, pushing charges from the negative pole toward the positive pole. f2 science electricity exercise top

Look at the circuit described below: A battery is connected to two bulbs, Bulb X and Bulb Y. They are connected side-by-side (parallel). A switch controls only Bulb X. a) Draw the circuit diagram using standard symbols. b) If Bulb X breaks, will Bulb Y still light up? Explain why. Mastering these questions does more than help you

Don't forget the safety features! You will likely be asked about: Look at the circuit described below: A battery

Which statement is true about a short circuit? A) Very high resistance, low current B) Very low resistance, high current C) High voltage, low current D) Open switch, no current
