部分真題預覽:
1)Students are given the circuit above in their lab, but they do not know the values of the two resistances RA and RB. The battery has a terminal voltage of 24 V and the inductor has an inductance of 0.05 H. Assume the internal resistance of both the battery and the inductor to be negligible. The switch S is closed at time t = 0.
In order to determine the values of the resistances RA and RB, the students measure the current as a function of time through the resistance RA. The graph of their results is below.
On the circuit diagram above, insert an ammeter to measure the current through RA.
Use the data taken by the students to calculate the value of RA.
Use the data taken by the students to calculate the value of RB.
Calculate the initial rate of change of current in the inductor.
In reality, both the battery and the inductor have nonnegligible internal resistance. Would the true value of RA?be greater than or less than the value you obtained in part (b)?
_______Greater than_______Less than
