a 75.0 pF capacitor is connected to a 12V battery. How much charge is on each plate?
Have you seen the equatiuon
Q = C*V ?
To calculate the charge on each plate of a capacitor, you need to use the formula:
Q = C * V
where Q is the charge, C is the capacitance, and V is the voltage.
In this case, the capacitance (C) is given as 75.0 pF, and the voltage (V) is given as 12V.
Let's calculate the charge on each plate:
Q = 75.0 pF * 12V
First, we need to convert the capacitance to farads (F) by converting pF to F:
1 pF = 1 * 10^(-12) F
So, 75.0 pF = 75.0 * 10^(-12) F
Now, let's substitute the values into the formula:
Q = (75.0 * 10^(-12) F) * 12V
Multiply the values:
Q = 900 * 10^(-12) F*V
Simplifying:
Q = 900 * 10^(-12) C
The charge on each plate is 900 picocoulombs (pC).
