Fill in Blank please.

The figure shows a circuit containing an electromotive force, a capacitor with a capacitance of C farads (F), and a resistor with a resistance of R ohms (ohm), The voltage drop across the capacitor is Q/C, where Q is the charge (in coulombs), so in this case Kirchhoff s Law gives But I = dQ/dt, so we have Suppose the resistance is 2 ohm, the capacitance is 0.05 F, a battery gives a constant voltage of 80 V, and the initial charge is Q = 0 C. Find the charge at time t. Find the current at time t. A tank with a capacity of 400 L is full of a mixture of water and chlorine with a concentration of 0.03 g of chlorine per liter. In order to reduce the concentration of chlorine, fresh water is pumped into the tank at a rate of 2 L/s. The mixture is kept stirred and is pumped out at a rate of 8 L/s. Find the amount of chlorine in the tank as a function of time.

Explanation / Answer

q=0.05*80*(1-e^(-10t))

i=40*e^(-10t)

m = 12*(1-0.015*t)^(4/3) gram
