Topics

Meter Readings Revision of current measurements using an analog

meter Draw a diagram of how to connect an ammeter in a

circuit containing a 10V dc source and a 1kΩ resistor – label your meter leads +ve and –ve

What settings should your meter have prior to turning on the power?

Please redo a couple of measurements from last week’s practical
