Figure 4.78 shows a circuit consisting of a lamp with a resistance of 11.7 Ω and a battery with internal resistance R_i = 0.3 Ω. Find: (a) the current drawn from the battery, (b) the voltage drop across the internal resistance R_i, (c) the terminal voltage of the battery, (d) the power dissipated internally by the battery, (e) the power delivered to the load, and (f) the efficiency of the battery.
