NEVER MIND! I realized my question is kind of stupid. Its night here and I am kind of sleepy.
a battery of 4V is connected opposite to a battery of 2V to charge the 2V battery. assume the current running through the circuit to be 2 Ampere. What is the Work done by
1) the Whole circuit
2) By the 4V battery
3) by the 2V battery
Work = Voltage x Charge
1) I know that 2 A is 2 Columb/second. and since the two batteries are opposite the whole circuit work done is (4 - 2)V x 2 Columb = 4 J
2) for part 2 and 3 I am not sure I I should consider each battery by its own or what to do?
Also if we do do consider both, Isn't the current flowing in the 2V in the opposite direction of its positive terminal therefore makes it negative Work done! (work done is scalar)
a little clarification and a little help with the question would be really appreciated
Thanks
