Question
A flashlight bulb carries a current of 0.16({ m A}) for 79({ m s}).Part A How much charge flows through the bulb in this time?
(Delta Q) =
( m C) Part B How many electrons? A flashlight bulb carries a current of 0.16({ m A}) for 79({ m s}).
A flashlight bulb carries a current of 0.16({ m A}) for 79({ m s}).
A flashlight bulb carries a current of 0.16({ m A}) for 79({ m s}).
Part A How much charge flows through the bulb in this time?
(Delta Q) =
( m C) Part A How much charge flows through the bulb in this time?
(Delta Q) =
( m C) (Delta Q) =
( m C) (Delta Q) =
( m C) Part B How many electrons? (Delta Q) =
( m C)
Explanation / Answer
i = Q/t
So, Q = i.t = 0.16 * 79 = 12.64 C
No of electrons = 12.64 / 1.6*10^-19 = 7.9 * 10^19 electrons
