the resistance of an unknown resistor is determined by the wheatson
bridge method, the solution for the unknown resistance is stated as
=
rx
where ri
r
rr/r;
500 2 +1%
615 82 + 1%
100 2 + 0.5%
=
r3
calculate (a) the nominal value of the resistor (b) the limiting error in ohms of the
unknown resistor, (c) the limiting error in percent of the unknown resistor.
or we tested to determine losses and efficiency, the
