Web26 okt. 2024 · If you’re adding or subtracting quantities with uncertainties, you add the absolute uncertainties. If you’re multiplying or dividing, you add the relative uncertainties. If you’re multiplying by a constant factor, you multiply absolute uncertainties by the same factor, or do nothing to relative uncertainties. Websize from 100% to 80%. Print graph. Using a straightedge locate the 1/e and the 1/e2 points and the defined times the for the discharge curves and label them on the graph. 5. Next, graph voltage versus time for each RC circuit on a semi-log graph, with voltage on the logarithmic (Y) axis and time on the linear (X) axis. Go to
WebThe correct option is B 1.15 While discharging q =q0e−t/τ So, U (t) = q2 2C = q02 2C⋅e−2t/τ And, U t=0 = q02 2C Let, after n time constants, the energy stored in the capacotor becomes ( 1 10)th of initial value. So, at t =nτ, U f = U i 10 i.e. q02 2C⋅e−2t/τ =(q02 2C)( 1 10) ⇒ e−2t/τ = 1 10 ⇒ e−2nτ/τ = 1 10 e−2n = 1 10 2n =loge10 2n =2.303 log1010 WebDepartment of Electrical and Electronic Engineering Faculty of ...
