Answer:
Explanation:
Given that,
A portable music player is operating with 4 cell batteries connected in series, and each cell has a P.D of 1.5V.
Then,
Total potential difference is
P.D_total = V1 + V2 + V3 + V4
P.D_total = 1.5 + 1.5 + 1.5 + 1.4
P.D_total = 6V.
The music player provides a resistance of 15,000Ω
R = 15,000Ω
We want to find the current (I) flowing through the music player?
Using ohms law
V = IR
Where
V is the potential difference
I is the current
R is the resistance
Therefore,
I = V/R
I = 6 / 15,000
I = 4 × 10^-4 A
I = 0.4 × 10^-3 A
I = 0.4 mA.
So, 0.4mA is passing through the music player
