A. Remains the same
B. Decreases
C. Increases
D. None of the above
A. series combination
B. parallel combination

D. none of above
Capacitor does not allow the sudden change of ?
A. current
B. voltage
C. power
D. None of the above
The expression of current through a capacitor is
For sudden change of voltage infinite current is required. But practically it is not possible.
Practical capacitor circuit has finite value of time constant
How many coulombs of charge flow through a circuit carrying a current of 10 A in 1 minute?
A. 10
B. 60
C. 600
D. 1200
1 Ampere current means flowing of 1 Coulomb charge per second. That means 10 A current in 1 minute or 60 seconds implies 10 × 60 = 600 coulombs.
A. negative
B. positive
C. zero
D. data is insufficient
A. 3
B. 5
C. 4
D. 6
A. A.C generator
B. D.C dynamo
C. induction coil
D. transformer
