To transform a wye circuit to an equivalent delta circuit, we use the following formulas:

Ra = (R1R2 + R2R3 + R1R3) / R1 Rb = (R1R2 + R2R3 + R1R3) / R2 Rc = (R1R2 + R2R3 + R1*R3) / R3

Given that R1 = 820Ω, R2 = 330Ω and R3 = 180Ω, we substitute these values into the formulas:

Ra = (820330 + 330180 + 820180) / 820 = 992Ω Rb = (820330 + 330180 + 820180) / 330 = 2466Ω Rc = (820330 + 330180 + 820*180) / 180 = 4521Ω

So, the equivalent delta circuit values are Ra = 992Ω, Rb = 2466Ω, Rc = 4521Ω. Therefore, the correct answer is option d.
