The no of electron passing through the circuit is current by time. The no of electron passing are 46.63 x 10¹⁹ electrons.
<h3>What is charge?</h3>
The charge is the physical quantity which attracts or repels another object when comes into its field.
The time 3 min has 3 x 60 =180 seconds.
Total Charge Q = current I x time t
Q = 0.415 x 180
Q =74.7 coulombs
The no of electrons is the ratio of total charge divided by the fundamental charge.
n = 74.7/ 1.602 × 10⁻¹⁹
n= 46.63 x 10¹⁹ electrons
Thus, electrons pass a given point in the circuit in 3 min are 46.63 x 10¹⁹ .

An observable phenomenon that is commonly associated with a spinning object moving through a fluid.
<span>a)
Capacitance = k x ε° x area / separation
ε° = 8.854 10^-12 F/ m
k = 2.4max
average k = 0.78 / 1.27 * 2.4 +(1.27- 0.78) / 1.27 * 1 = 1.474 + 0.386 = 1.86
(61.4 % separation k = 2.4 --- 38.6 % k = 1 air --- average k = 0.614 * 2.34 + 0.386 * 1 = 1.86
area = 145 cm2 = 0.0145 m2
separation = 1.27 cm 0.0127 m
C = 1.86 * 8.854 10^-12 * 0.0145 / 0.0127 = 18.8 pF
b) Q = C * V --- 18.8 * 83 = 1560.4 pC = 1.5604 nC
c) E = V / d = 83 / 0.0127 = 6535.4 V/m </span>
