Question

Can anyone please help me it’s easy but i’m just confused

Answer 1

Hello!

1.

b)

i)

We can calculate the charge flow using the following relation:

`Q = I * t`

Q = Total charge (C)
I = Current (A)
t = time (s)

Plug in the given values to solve.

`Q = 2 * 300 = \boxed{600 C}`

ii)

We can calculate the total electrical energy using the equation:

`E = (1)/(2)QV`

Q = Charge (C)
V = Potential difference (V)
E = Energy (J)

Plug and solve.

`E = (1)/(2)(600 * 12) = \boxed{3600 J}`

2.

a)
We can use the same equation as above to solve for the charge.

`Q = I * t\\\\Q = 0.20 * 20 = \boxed{4 C}`
