A heavy turntable is mounted on a fixed base. The turntable can rotate freely on a low-friction bearing. Figure 1 shows a propeller unit fixed to the centre of the turntable. The propeller unit consists of a motor-driven propeller and a battery. The propeller and the turntable ha…
Conductive putty can easily be formed into different shapes to investigate the effect of shape on electrical resistance. 1 A student uses vernier callipers to measure the diameter $d$ of a uniform cylinder made of the putty. Suggest one problem with using callipers to make this m…
An analogue voltmeter has a resistance that is much less than that of a modern digital voltmeter. Analogue meters can be damaged if the full-scale reading is exceeded. Figure 6 shows a dual-range analogue voltmeter with a zero error. Figure 6 1 The voltmeter is set to the more se…
