A resistorâcapacitor circuit (RC circuit), or RC filter or RC network, is an electric circuit composed of resistors and capacitors driven by a voltage or current source. A first order RC circuit is composed of one resistor and one capacitor and is the simplest type of RC circuit.RC circuits can be used to filter a signal by blocking certain frequencies and passing others.s : So at DC (0 Hz), the capacitor voltage is in phase with the signal voltage while the resistor voltage leads it by 90Â°. As frequency increases, the capacitor voltage comes to have a 90Â° lag relative to the signal and the resistor voltage comes to be in-phase with the signal.

Carbohydrates Do More Than Make Energy for Your Body Carbohydrates Do More Than Make Energy for Your Body Making energy isnât the only thing your body does with the carbohydrate nutrients in your diet. Carbohydrates also protect your muscles. When you need energy, your body looks for glucose from carbohydrates first. If no glucose is available, because youâre on a carbohydrate-restricted diet or have a medical condition that prevents you from using the carbohydrate foods you consume, your body begins to pull energy out of fatty tissue.
