When two resistors are connected in parallel across a battery of unknown voltage, one resistor carries a current of 3.2 amps while the second carries a current of 1.8 amps. What current will be supplied by the same battery if these two resistors are connected to it in series? V=IR well the voltage received by each is the same in the parallel setup.. i thought i could do a IR=IR setup.. but that just confused me.. but i think i need to do something with the ratio of the currents hrmm. 1.8/3.2. but I am not sure where to go. Any hints?
