Show hintHide hint
Remember the key variables in the formula.
3Question 3.
What is the primary function of a capacitor?
- To generate energy
- To store electric charge
- To convert energy
Show hintHide hint
Consider the role of capacitors in circuits.
4Question 4.
True or False: Doubling the distance between plates in a parallel plate capacitor will double its capacitance.
- True
- False
Show hintHide hint
Think about how the formula relates distance to capacitance.
Question 5.
A parallel plate capacitor has a plate area of 0.25 m² and a plate separation of 1 cm. If the permittivity of free space is 8.85 x 10⁻¹² F/m, calculate its capacitance.
Show hintHide hint
Ensure you convert the separation into meters before calculating.
Question 6.
If a dielectric with K = 3 is added to the capacitor described previously, what is the new capacitance?
Show hintHide hint
Just multiply the original capacitance by the dielectric constant.
