# Demoivre’s Theorem – Integral and Rational Indices

Demoivre’s Theorem – Integral and Rational Indices For any real number q and any integer n, (cosθ + i sinθ)ⁿ = cos nθ + i sinnθ If n is a rational number, then one of the values of (cosθ + i sinθ)ⁿ  is cos nθ + i sinnθ. Note: (i) it is customary to write Read more about Demoivre’s Theorem – Integral and Rational Indices[…]

# AC Voltage applied to a Capacitor

AC Voltage applied to a Capacitor When a capacitor is connected to a voltage source in a dc circuit, current will flow for the short time required to charge the capacitor. As charge accumulates on the capacitor plates, the voltage across them increases, opposing the current. That is a capacitor in a dc circuit will Read more about AC Voltage applied to a Capacitor[…]
