Hello ACC Forum,
This is pretty basic question.
Measuring the current flowing thru an LED. The specs say 20 mA. Need to
light 292 and interested in how many amps they will draw.
So a simple circuit was fashioned: a voltage source, a resister, and an LED.
The circuit was then broken and a connection to the multimeter inserted
But the multimeter says all zeros.
The multimeter is set to the lowest setting available
but no current is measured.
Could it be that 20mA is to small an amount of
current for the multimeter to measure?
Thanks.
Allen
