Hello
, you know what to do next.
in a circuit for a potential divider which calculates voltage drops, i nned to transpose it so that i can calculate resistances.
The existing formula is
v=(R1/RT)(V)
where v is voltage drop across a resistor (9.38 Volts) and V is source voltage(10 volts), R1=75k ohm, R2=5k ohm, RT=R1+R2. How would I make R1 the subject? Thanks
