Practice Problems

Problem 1

A capacitor stores 0.01 C of charge when connected to a 10V battery. What is its capacitance?

Problem 2

Find the equivalent capacitance of two 2μF capacitors connected in series.

2μF 2μF I C_eq 1/C_eq = 1/2μF + 1/2μF = 1μF

Problem 3

Find the equivalent capacitance of two 2μF capacitors connected in parallel.

2μF 2μF I_total I₁ I₂ V (same) C_eq C_eq = 2μF + 2μF = 4μF

Problem 4

A 10μF capacitor is charged to 5V. What is the energy stored in the capacitor?
