Answer:
the charge generated in the circuit is 240 C.
Explanation:
Given;
current flowing in the circuit, I = 2A
time of current flow, t = 2 minutes = 2 x 60s = 120 s
The current flowing through a given circuit is defined as the quantity of charge flowing through the circuit in a given time.
where;
Q is the charge flowing in the circuit
Q = 2 x 120
Q = 240 C
Therefore, the charge generated in the circuit is 240 C.
Answer:
2. +0.2 C
Explanation:
When the two spheres touch, the total charge will be redistributed such that the two spheres are at same potential:
The potential can be rewritten as ratio between the charge on the sphere (Q) and the capacitance of the sphere (C):
Since the two spheres are identical, they have same capacitance:
So we can write
And since the total charge is
And this charge will be redistributed equally on the two spheres (), we have
