So 10 ohms matches the peak current seen through the coil immediately during startup (6V/10 ohms = 0.6A) So I am mot seeing why the same situation (6V rather than 3V) does not exist during stall?

<Moderator note: Moved from General Physics.> Hi there I have an audio generator (pic attached) with an internal speaker which is very low volume. I have a microphone and CRO and I would like to view the sound waves. The output on the audio generator says 600 ohms. Are these output terminals...

Does the spark frequency = the interruptor frequency = radio signal frequency. From the sources I have found these frequencies don't seem to match. We use a 9V DC one at school. Many Thanks
