3.7.5.5 Alternating currents (A-level only)
| Content | Opportunities for skills development |
|---|---|
Sinusoidal voltages and currents only; root mean square, peak and peak-to-peak values for sinusoidal waveforms only. |
Application to the calculation of mains electricity peak and peak-to-peak voltage values.
Use of an oscilloscope as a dc and ac voltmeter, to measure time intervals and frequencies, and to display ac waveforms.
No details of the structure of the instrument are required but familiarity with the operation of the controls is expected.
