<u>Answer:</u> The charge on each plates is
.
<u>Explanation:</u>
The magnitude of charge that flows through the plates is directly dependent on the capacitance and the voltage flowing through the plates.
Mathematically,

where,
Q = charge flowing = ? C
C = capacitance =
(Conversion Factor:
)
V = Voltage across the plates = 12 V
Putting values in above equation, we get:

Hence, the charge on each plates is
.
Answer;
light fixtures
Explanation;
Radioactive isotopes have a variety of applications. They are useful because either we can detect their radioactivity or we can use the energy they release.
These uses includes;
