Each one sits inside its topic page, next to the notes it goes with.
Oscilloscope
Set the Y-gain and time-base, then read the peak voltage, period, frequency and rms.Monitoring & measuring a.c.
Series & parallel
Enter resistor values, choose the arrangement, and see the total resistance worked out.Current, p.d., power & resistance
Potential divider
Change the resistors and supply, or swap in a sensor, and watch V2 follow.Current, p.d., power & resistance
EMF & internal resistance
Change E and r and watch the V–I line tilt. Read the EMF and internal resistance off it.Electrical sources & internal resistance
Charging a capacitor
Change R and C and watch the charging curves. A bigger R or C charges more slowly.Capacitors
Our Dynamic Universe
Special relativity
Light clocks show why a moving clock runs slow; a rocket and ruler show length contraction. With worked examples and practice.
More with each topic page
Motion, forces and gravitation get theirs as their topic pages are built.
Particles & Waves
Coming with the topic pages
These arrive as each Particles & Waves page is built.
