This problem has 3 parts.

A single resistor with resistance R ohms is connected to a battery.

part a - If the single resistor is replaced with 2 identical resistors each of R ohms connected in series, will the battery have to provide more power, less power or the same? Explain your choice, include any equations that apply.

part b If instead of connecting the two resistors in series, they are connected in parallel, will the battery have to provide more power, less power or the same power as with the single resistor? Explain your choice, include any equations that apply.

part c If you compare the currents through each of the circuits: original circuit, part a circuit and part b circuit, will any of the circuits have a current larger than the other two or will they be the same. Explain your choice, include any equations that apply.

A resistor of resistance R and a capacitor of capacitance C are connected in series to an EMF of voltage E. A switch is set to the open position and the capacitor is initially uncharged. The switch is then closed. Show that when the capacitor charges that half of the energy drawn from the EMF is dissipated in the resistor and that half of the energy is stored in the capacitor.

This problem deals with the RC circuit shown to the right containing a resistor (R ohms), a capacitor (C farads), a switch, a source of emf, but no inductor. The differential equation for this circuit is given below. R(dQ/dT)+1/c(Q)=E(t) this is an equation for the charge Q(t) on the capacitor at time t. Note that I(t)=Q'(t). Use the values R=100, C=5.0x10^-4, Q(0)=0, and E(t)=100cos120t to find (a) and (b) below: a: find Q(t) and I(t) b: What is the amplitude...
