Replacing Resistors in Series: Equivalent Resistance and Calculation

AI Thread Summary
Two resistors in series can indeed be replaced by a single resistor that provides equivalent resistance to the circuit. The relationship is defined by the formula R_eq = R1 + R2, where R_eq is the equivalent resistance. When replacing the series combination with one resistor, it does not remain in series with anything else in the circuit. The discussion also emphasizes the importance of clear communication to avoid repetitive questions. Understanding the calculation of equivalent resistance is crucial for circuit analysis.

Can two resistors in series be replaced by a single resistor and give an equivalent resistance to the circuit?

If so , how must the single resistance be related to the two in series ?
R=R1+R2 ? ?

My answer is yes they can be replaced by a single equivalent resistance

buthow must the single resistance be related to the two in series ?

will it be in series !?
 
i mean do we use R=R1+R2? is this the answer ?
 
Yes, that's the answer. But I don't understand this: "will it be in series !?" Will it be in series with what? If you're replacing the whole series by one resistor, no.
 
yup that's right. R_e_q_u=R_1+R_2
 
mich_v87, I've merged your 2 identical questions. Could you please refrain from doing so in the future (except for accidental posting) ?

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
