Module 6 Chapter 1 - Capacitors Flashcards
1
Q
What is the equation to calculate the capacitance of a capacitor and what is the unit?
A
C = Q/V, measured in farads.
2
Q
What is the method for calculating the capacitance of multiple capacitors in parallel?
A
Ct = C1 + C2 … + CN
3
Q
What is the equation for the energy stored in a capacitor?
A
W = 1/2 QV. This is the area under a Q-V graph.
4
Q
What is the equation for the discharging of a capacitor?
A
x = xₒ e⁻ᵗ/τ
5
Q
What is the equation for the charging of a capacitor?
A
x = xₒ (1 - e⁻ᵗ/τ)
6
Q
What is the equation for the time constant for a capacitor-resistant circuit?
A
τ = CR
