Answer:
<em>The current is 11 Amperes</em>
Explanation:
<u>Electric Current</u>
The electric current is defined as a stream of charged particles that move through a conductive path.
The current intensity can be calculated as:
Where:
Q = Electric charge
t = Time taken by the charge to move through the conductor
The current intensity is often measured in Amperes.
The charge passing through a point in a circuit is Q= 55 c during t=5 seconds, thus the current intensity is:
I = 11 Amp
The current is 11 Amperes
Answer:
The number of excess electrons on each sphere is 759
Explanation:
Given that,
distance , d = 20 cm
= 0.20 m
let the number of electrons is n
Electric force (F) = k × (n × e)² /d²
3.33 × = 9 ×
× (n × 1.602 ×
)² /0.2²
solving for n
n = 759
