Flashcards do conjunto (11)
- 1ActivityA = λN
λ = Decay Constant
N = Number of undecayed nuclei - 2Rate of Decay (Graph Plot)\(\frac{dN}{dt}\) = -λN
- 3Number of undecayed nuclei remainingN = N0\(e^-λt\)
- 4Activity changing with timeA = A0\(e^-λt\)
- 5Half LifeT\(\frac{1}{2}\) = \(\frac{ln2}{λ}\)
- 6Half Life in terms of NN = N0\((0.5)^n\)
- 7CapacitanceC = \(\frac{Q}{V}\)
- 8Energy StoredE = \(\frac{1}{2}\)QV
E = \(\frac{1}{2}\)C\(V^2\)
E = \(\frac{1}{2}\)\(\frac{Q^2}{C}\) - 9Current and DischargeI = \(\frac{V}{R}\) = \(\frac{Q}{CR}\)
ΔQ = -IΔt
\(\frac{ΔQ}{Δt}\) = -\(\frac{Q}{CR}\)
