1.	A storage battery with emf `2.6 V` loaded with external resistance produces a current `1 A`. In this case, the potential difference between the terminals of the storage battery equals `2 V`. Find the thermal power generated in the battery and the net power supplied by the battery for external circuit.
Answer» Correct Answer - B `V=E-ir` `:. r=(E-V)/i=(2.6-2)/1` `=0.6Omega` Now, power generated in the bttery `P=i^2r` `=(1)^2(0.6)=0.6W` Power supplied by the battery `=Ei` `=2.6W` `:.` Net supplied for external circuit `=2.6-0.6=2.0W`
