Question

1. Why is it L/R not LR for the charging and discharging a series RL circuit? 2. In the determination of C in Part II, what will you observe if the voltage probe is connected across RD? Can you determine capacitance from this? across the terminals of the inductor? Can you determine inductance from this? graphs do you expect in the RC and RL circuit? 3. In the determination of L in Part III, what will you observe if the voltage probe is connected 4. If a sinusoidal signal is used instead of square wave in the function generator, what kind of

Explanation / Answer

All the 2,3,4 part are related to an experiment which is not mentioned here, so it wont to possible to answer these below three at this point of time. and I am answering question no 1 here.

1) In series L-R-C circuit, either inductor or capacitor, one of them is dominating over other and that is why the circuit behave as either capacitive or inductive based on their dominance. and whether current is leading in the circuit over voltage or legging , this also depend on whether circuit is inductive or capacitive.

so this is why we use l/r instead lr .
