Weba) Series: i) 0.6 V (12 ÷ 20) [1] because the supply voltage is shared in series circuits. [1] ii) All the other bulbs will be off [1], there is a break in the circuit. [1] Parallel: i) 12 V because the same voltage is across each bulb irrespective of the quantity. [1] ii) All the other bulbs will remain on at the same brightness as there is more than one path for the current to flow. Weblimit the flow of current around a circuit and can prevent damage to components. Resistors used in electrical circuits have a tolerance of how much power they allow into a circuit - the smaller that tolerance is, the less likely the circuit will be overloaded and damaged, but the more expensive the resistor will be.
