1. Alternating-Current Circuits Physics 1112

2. Alternating current is commonly used everyday in homes and businesses throughout the word to power various electrical appliances

3. The voltage supplied by an AC source is sinusoidal with a period T Voltage in AC Circuits

4. Resistors in AC Circuits

5. RMS Current & RMS Voltage Average value of current is referred as RMS Current & average value of voltage is referred as RMS Voltage The notation rms stands for root-mean-square, which means the square root of the mean (average) value

6. Inductors in an AC Circuit Instantaneous current and voltage are out of phase by  /2  L is defined as inductive reactance X L

7. Capacitors in an AC Circuit Instantaneous current and voltage are out of phase by  /2 (1/  C) is defined as capacitive reactance X C

8. The RLC Series Circuit

9. Z is called impendence of circuit

10. Resonance in a Series RLC Circuit The angular frequency at which X L -X C =0 is called the resonance frequency of the circuit
