When a 100-ω resistor is connected across the terminals of a battery of emf ε and internal resistance r, the battery delivers 0.794 w of power to the 100-ω resistor. when the 100-ω resistor is replaced by a 200-ω resistor, the battery delivers 0.401 w of power to the 200-ω resistor. what are the emf and internal resistance of the battery? (a) ε = 10.0 v, r = 5.02 ω(b) ε = 12.0 v, r = 6.00 ω(c) ε = 4.50 v, r = 4.00 ω(d) ε = 9.00 v, r = 2.04 ω(e) ε = 9.00 v, r = 1.01 ω
