Advancing Physics OCR - Tomorrow - Insert Question
Hi
I was wondering if anybody could help with a question regarding the insert for G492 tomorrow.
The two diagrams - (digital and analogue signal) - what is the uncertainty and resolution for the two?
Any help appreciated
Thanks

Analogue, uncertainty is ±5%, resolution is the smallest noticable change, so its ±1 or ±0.5 should you use a magnifying glass.
Digital, Uncertainty is ±0.01%, resolution is ±0.1A
Good luck!

Thankyou for your reply
I understand the analogue, but for the digital, how come the resolution is 0.1A when it can read to 2 decimal places? Original post by Jack976
