Two students measure the time constant of an RC circuit. The first student charges the capacitor using a 12 V battery, then lets
luda_lava [24]

Answer:

The answer is: c.) Both students get the same time constant, since the time constant does not depend on the charge on the capacitor

Explanation:

Both students, because the time constant is not dependent on the capacitor charge.  We can express the equation of the time constant as follows:

Time constant = RC

In this equation it is observed that the time constant is equal to the multiplication of the resistance (R) multiplied by the capacitance (C)

Which of the following equations defines the law of conservation of energy?
loris [4]
NONE of those choices defines the law of conservation of energy,
and none even describes it.  It's as if these choices belong to
a whole different question. 

In fact, none of the choices is even a true statement by itself !

A statement that defines the law of conservation of energy
would have to say something like this:

The total amount of energy in any closed system is constant.
The total amount of energy after any event or process is the
same as the total amount was before it.
