WebEnter two time values or one time value and the percentage. The line left empty will be calculated. Example: if you sleep 7 hours and 45 minutes (time 1) a day (time 2: days=1), you slept 32.29% of the day. For questions like: in a certain time span x, y% are done, how long does it take to reach 100%, see Rule of Three with Time Values. 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
