//2000 = turns on secondary coil
//((100000+10000)/10000), voltage reduction bridge
//30 because the clamp is a 30A/1V
//Primary peak-current = RMS current × √2 = 100 A × 1.414 = 141.4A
//c) Divide the peak-current by the number of turns in the CT to give the peak-current in the secondary coil.
//The YHDC SCT-013-000 CT has 2000 turns, so the secondary peak current will be:
//Secondary peak-current = Primary peak-current / no. of turns = 141.4 A / 2000 = 0.0707A
//d) To maximise measurement resolution, the voltage across the burden resistor at peak-current should be equal to one-half of the Arduino analog reference voltage. (AREF / 2)
//If you're using an Arduino running at 5V: AREF / 2 will be 2.5 Volts. So the ideal burden resistance will be:
//Ideal burden resistance = (AREF/2) / Secondary peak-current = 2.5 V / 0.0707 A = 35.4 Ω

//Primary current = 2000 * secondary current = 2000 * AREF/2 / Burden resistance
