Explain a comparison within its limits - Paper 2
Read the information, then answer the questions. An adult may read the instructions aloud. Show your working where asked.
Read before answering
Invented circuit comparison F: same approved supply; one lamp then two identical lamps in series. Observation: two lamps each appear dimmer. In a suitable fixed-supply circuit, two identical lamps in series usually each appear dimmer than a single lamp. A conclusion needs the actual connections and component details. Analyse these records only; physical work requires adult-approved low-voltage equipment.
