a) How does the charge Q depend on time t? \(Q(t)=\) %chq(0)
The resistor, over which the capacity discharges, is R={{g.r}}\(k\Omega\). At time t=0s we measure a voltage at the capacitor of {{g.u}}V, and at t={{g.t}}s the voltage is {{round(g.u2,2)}}V.
b) Find the capacity of the capacitor? \(\frac{C}{μF}=\) %chq(1)
c) What is the charge at t=0s? \(\frac{Q_o}{As}=\) %chq(2)
d) What is the charge at t={{g.t}}s? \(\frac{Q_t}{As}=\) %chq(3)
e) After how many second is the fully loaded capacitor only half loaded? %chq(4)
