In Fig. 27-26, the ideal batterieshave emfs E1=150 V and E2=50 Vand the resistances are R1 = 3.0 0 andR2 = 2.0 0. If the potential at P is 100 V,what is it at Q?
Why would batteries with high current capacity have a lower internal resistance than batteries with a low current capacity? Consider the difference between 12 V car batteries and 12 V flashlight batteries. While both batteries supply the same voltage (12 V) of EMF, they have considerably different applications. Use V = E - Ir to explain the answer
In the circuit shown in the figure, the S switch closed at t=0 and the capacitors, which are completely empty, begin to fill. Here ε=10 V, C=5 μF and R=55 Ω.
What is the time constant of the circuit, τ, in units of microseconds?
When t= τ, what is the total charge, in units of microcoulomb, accumulated in the capacitors?
