B
Explanation:
They are the BASE elements. Cannot make them any simpler.
Answer:
(a) I = 0.6 A
(b) 22.5 * 10^19 electrons
Explanation:
Parameters given:
(a) Current is given as the time Tate of charge flow. Mathematically,
I = Q/t
Charge, Q = 3 C
Time, t = 5 secs
I = 3/5 = 0.6A
(b) The current flowing through the filament is 0.6A. In 1 min (60 secs), the charge will be:
Q = I*t
Q = 0.6 * 60 = 36 C
An electron has a charge, Qe, of 1.6022 * 10^(-19) C. Hence, the number of electrons will be:
N = Q/Qe
N = 36/(1.6022 * 10^(-19))
N = 22.5 * 10^19 electrons
