Hi,
- I tried to measure the current of a dc source (with specifications: 5V/200mA) by connecting the ammeter's +ve with the +ve of dc source and ammeter's -ve with the -ve of the dc source. However, the current shown was less than the actual 200mA. The measured current was about 130mA.
- Across a source of 25V a series combination of a 10MOhm resistor and Ammeter is connected. A Voltmeter is also connected in parallel to the source. With this setup the Ammeter shows no current! The Multimeter used as Ammeter & Voltmeter can be seen **broken link removed**. Can anyone help in this regard?
- Can someone give me advice about measuring current especially with very less amount i.e. in uA?
