एक वैद्युत द्विध्रुव का स्थिर द्विध्रुव आघूर्ण `vec(P)` है जो कि X-अक्ष से `theta` कोण बनता है। वैद्युत क्षेत्र `vec(E)_(1) = E hat(i)` में रखने पर यह बल आघूर्ण `vec(tau)_(1) = tau hat(k)` का अनुभव करता है। वैद्युत क्षेत्र `vec(E)_(2) = sqrt3 E_(1) hat(j)` में रखने पर यह बल-आघूर्ण `vec(tau)_(2) = - vec(tau)_(1)` का अनुभव करता है। कोण `theta` का मान होगा:
