I WANT TO INTERFACE A 200:5 CURRENT TRANSFORMER WITH A LOW POWER CIRCUITRY SUCH AS ADE7758 WHICH REQUIRES .5 V PEAK MAX AS AN INPUT OF ITS ADC.I CALCULATED THE BURDEN RESISTOR TO BE 36 mOHM WHICH IS NOT AVAILABLE SO I THOUGHT OF PLACING AN ARRAY OF 28 PARALLEL RESISTORS OF 1 OHM SO THAT THEIR PARALLEL EQUIVALENT BE 36 mOHM.WHAT WILL BE THE CONSEQUENCES.WILL IT WORK FINE?WONT THE HEAT DISSIPATION BE TOO MUCH OR ITS POSSIBLE WITH A LOW POWER CIRCUITRY SUCH AS ADE7758?
