"Q = ΔU + W" is the equation is used to solve the questions related to "First law of thermodynamics".
<h3> What is the first law of thermodyanamics?</h3>
"First law of thermodynamics" states that "energy" neither created nor destroyed, but it can transfer from "one form of energy" to "another form of energy".
This "First law of thermodynamics" is also called as "law of conversation of energy". The formula for "First law of thermodynamics" of a system is that "change in internal energy of a system" is same as the difference of "heat energy" flows across the " boundaries of a system" and the "work done" on the system.
ΔU = Q - W
Q = ΔU + W
Where, "ΔU" is "change in internal energy", "Q" is "heat transferred and "W" is "work done.
Hence "Q = ΔU + W" is the equation is used to solve the questions related to "First law of thermodynamics".

I did it last year. I thinks its A
Answer: Neither of them is correct because the other bulb will not work
Explanation: In a series circuit, the current that flows through each of the components is the same, and the voltage across the circuit is the sum of the individual voltage drops across each component. This is the other way for a parallel circuit connection
In a series circuit, every device must function for the circuit to be complete. If one bulb burns out in a series circuit, the entire circuit is broken. In parallel circuits, each light bulb has its own circuit, so all but one light could be burned out, and the last one will still function.

75 because 25 plus 75 equals 90
