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?
In Fig. , the battery has negligible internal resistance and E = 48.0 V. R1 = R2 = 4.00 Ω and R4 = 3.00 Ω. What must the resistance R3 be for the resistor network to dissipate electrical energy at a rate of 295 W?
The switch on an RC circuit is closed at t = 0.Given that E = 9.0 V, R = 99 Ωand C = 28 μF , how much charge is on the capacitor at time t= 4.2 ms?
