The two combinations have the same resistance, (2 pt) Which is(are) true? The emf of a source of electric potential energy is A. the amount of electric energy delivered by the source per coulomb of positive charge as this charge passes through the source from the low to...
When resistors are in series, each resistor has the same current but the voltage is different for each according to Ohm’s Law. A given circuit consists of two resistors in series connected to a 24.0-V battery. The current in the circuit is 0.0320 A. If R_1=250.0 Ω,and R_2=500.0 Ω. Find the potential difference across each resistor. Find the equivalent resistance. If the circuit in Problem 6 above is reconnected with the two resistors in parallel, the...

Two cylindrical resistors are made of copper (p=1.72x10^-8 ohm m). R1 has radius 2.00mm and length 1.00m. R2 has twice the radius of R1. (a) Resistance of R1? (b) length of R2 if it has the same resistance (c) find how much current flow if either resistor were connected to 15V battery. (d) what is the current density through each resistor? (e) what is the current out of the battery if the resistors are connected in series?
When two resistors are wired in series with a 12 V battery, the current through the battery is 0.30 A. When they are wired in parallel with the same battery, the current is 1.6 A. What are the values of the two resistors? Note: I understand other people have asked the same concept with different numbers, and their questions have been answered, however I do not understand why you need to multiple R1 by R2 when the resistors are in...
A resistor (resistance = R) is connected first in series and then in parallel with a 2.56 Ω resistor. A battery delivers ½ times as much current to the series combination than it does to the parallel combination. Determine the two possible values for R.
A resistor (resistance = R) is connected first in parallel and then in series with a 1.53 resistor. A battery delivers 7 times as much current to the parallel combination as it does to the series combination. a) Determine the two possible values for R, the greater value being the answer to part (a). b) please include units for both potential difference
