27) The CT and burden resistor series circuit must produce 2V output given the
current calculated in step 26. Calculate and document the resistance value that
will produce 2V given the current of step 26. For the example above:
Ohms81.3
Amps525.0
Volts0.2

Actual Burden Resistor value = ________________ Ohms.
28) Perform a calculation for the power dissipation rating of the burden resistor
(I*I*R). Use the current and resistance values calculated in steps 26 and 27. For
the example calculation:
(0.525 Amps) * (0.525 Amps) * (3.81 Ohms) = 1.05 Watts
As a precautionary measure, use a burden resistor with a power dissipation rating
of at least twice the power dissipation rating calculated in step 28.
