[S4 Physics PMCians]
What we did in 2 hours:
Last lesson was all about DC circuits! By now, all of you should be familiar on using Ohm’s law in a DC circuit. But more importantly, you will know how to apply the shortcut methods of Potential divider (for components in series) and Current divider (for components in parallel). We also learnt about special resistors (aka transducers) such Thermistor and Light-dependent resistor (LDR), in which their resistance varies with temperature and light intensity respectively.
What you take home:
This is the same circuit builder simulator which we sent out a few weeks back, but this time, go to LAB and try constructing a series or parallel circuit, and predict the current or potential difference across the components using the ammeter or voltmeter respectively. Play around with it and try different combinations without having to go into an actual lab. =)
