1v / 0.001= 1000ohm resistor?10v / 0.001= 10000 ohm resistor.Like that?
Hint: if you measure 0.1V with 100uA meter FCD, it has RO=0.1V/0.0001=1kohm resistance itself. R1 must be such it creates a volatage divider 10:1
Study "voltage divider" or "resistive divider".
Study "voltage divider" or "resistive divider". It is your homework, isn't it?
QuoteStudy "voltage divider" or "resistive divider". In a voltmeter, they're called "multipliers".Two resistors in series, with an applied voltage of 10 volts give a current of 100uA.One of the resistors is 1000 ohms. Solve for the other series resistor.
or i'd be asking a professional who would give me the answer to R1 .
