The figure above shows a circuit containing an electromotive force (a battery), a capacitor with a capacitance of C farads (F), and a resistor with a resistance of R ohms (Omega). The voltage drop across the capacitor is Q/C, where Q is the charge (in coulombs), so in this case Kirchhoff's Law gives
RI + (Q/C) = E(t)
since the current is I = (dQ/dt), we have
R(dQ/dt) + (1/C)Q= E(t)
Suppose the resistance is 30 ohms, the capacitance is 0.1 Farads, a battery gives a constant voltage of 40 volts, and the initial charge is Q(0)=0C.Find the charge and the current at time t.
Q(t)=?
I(t)=?
What resistance, R, should be placed in series with the galvanometer, G, if it is to show a full deflection when the potential across the resistor is 6 V. The maximum current through the galvanometer is 250 mA and its internal resistance is 3 Ω.
(a) 24 Ω
(b) 23 Ω
(c) 3 Ω
(d) 5.25 Ω
(e) 21
A capacitor, C, is (fully) charged by connecting it to a 7 Volt EMF and then is allowed to dischargethrough a 2 Ω resistor as shown in the Figure. What is the current, I, in the circuit (in A) when thestored energy in the capacitor has dropped to 30% of its initial value?
