In an AC circuit with resistance R and oscillating potential v = vm sinωt, the average current over a cycle is

In an AC circuit with resistance R and oscillating potential v = vm sinωt, the average current over a cycle is Correct Answer zero 

CONCEPT:

  • The oscillating potential of an AC circuit is given by

⇒ v = vm sinωt

where 'vm' is the amplitude of the oscillating potential difference and 'ω' is the angular frequency

Important Points

  • The average current and potential difference in an AC circuit over a complete cycle are zero.

Questions below followed by three quantities. Find the relationship between them. Quantity I: In a class with a certain number of students if a teacher weighing 78 kg is added, then average weight of class is increased by 2 kg. If one more teacher weighing 66 kg is added, then the average weight of the class increases by 3.5 kg over the original average. What is the original average weight (in kg) of the class? Quantity II: The average age of 16 students and their teacher's age is 16 years. If the teacher's age is excluded, the average reduces by 2. What is the teacher's age? Quantity III: Average weight of three friends A, B and C is 46 kg. Another person D joins the group and now the average is 45 kg. If another person E whose weight is 6 kg more than D, joins the group replacing A, then average weight of B, C, D and E becomes 47 kg. What is the weight of A (in kg)?
Quantity I: The average age of a cricket team of 11 players is x years.
