A 0.25 uF capacitor is connected to a 9.0 V battery. What is the charge on the capacitor?
2.2*10^-6 C
correct
To calculate the charge on a capacitor, you can 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 is given as 0.25 uF (microfarads) and the voltage is 9.0 V.
Plugging in the values into the formula:
Q = (0.25 * 10^-6 F) * 9.0 V
Q = 2.25 * 10^-6 C
So, the charge on the capacitor is 2.25 * 10^-6 C
