SUMMARY

This discussion addresses the calculation of current supplied by a battery when two resistors are connected in series after being connected in parallel. The first resistor carries a current of 4.3 A and the second carries 3 A when connected in parallel. The total current supplied by the battery in series is equal to the sum of the individual currents, which is 7.3 A. The key takeaway is understanding the difference in current behavior between parallel and series resistor configurations.

Parallel vs. Series...HELP!

Homework Statement


When two resistors are connected in parallel across a battery of unknown voltage, one resistor carries a current of 4.3 A while the second carries a current of 3 A. What current will be supplied bu the same battery if these two resistors are connected to it in series?

In series the amps are the same throughout every resistor. In parallel the amps all add up to a total amperage. I'm pretty sure I know how to do it..see if you can figure out the rest.
