A 4-arm bridge network, adjusted to balance conditions, consists of; arm AB a standard resistor known to be within 0.1% of 1002 arm BC a variable condenser adjusted to 0.362µF in parallel with a variable resistor HA adjusted to 2380Q. arm CD a standard resistor known to be within 0.1% of lul. arm DA a coil of inductance L and series loss resistance R. Evaluate Land R, deriving the equations used. Determine the maximum percentage error that can be tolerated in each of the variable components if L is to be determined to within 0.5% and R to within 1% of the correct value. If the variable components are known to be accurate within the limits so determine how accurately is the ratio L/R known.
