Increasing the voltage across the two plates of a capacitor will produce what effect on the capacitor?



a. increase charge

b. decrease charge

c. increase capacitance

d. decrease capacitance

how do i approach this one?

To approach this question, you need to understand the basic principles of a capacitor. A capacitor is an electronic component that stores electrical energy in the form of an electric field between two conductive plates. The amount of charge that a capacitor can store is determined by its capacitance.

Now, let's analyze the options:

a. Increase charge: This option suggests that increasing the voltage across the capacitor will increase the amount of charge it can store. This is correct because the charge on a capacitor is directly proportional to the voltage. So, if you increase the voltage, you will increase the charge.

b. Decrease charge: This option suggests the opposite, that increasing the voltage will decrease the charge. However, this is incorrect because increasing the voltage on a capacitor will increase the charge, not decrease it.

c. Increase capacitance: This option suggests that increasing the voltage will increase the capacitance of the capacitor. However, this is incorrect. Capacitance is a property of the capacitor itself and does not change with voltage. Increasing the voltage only affects the amount of charge that the capacitor can store, not its capacitance.

d. Decrease capacitance: This option suggests that increasing the voltage will decrease the capacitance of the capacitor. However, this is also incorrect since, as mentioned earlier, the voltage does not change the capacitance of a capacitor.

Therefore, the correct answer is a. Increasing the voltage across the two plates of a capacitor will produce an effect of increasing the charge on the capacitor.
