Default Re: Testing DDl's circuit

No way...I'm not going to give 100mA
I have fobia of 100mA
I'll give about 90mA *

Default Re: Testing DDl's circuit

You can measure voltage drop on 1ohm resistor, so voltage drop=current.
If there is volt drop of 0.1V, current is 0.1A.
R=U/I
1=0.1/?
So, current is equal to voltage drop on 1ohm resistor.

Digital volt meter, sometimes called a multimeter as it measures more than just volts.
