Two resistors (R1 =3Ω&R2 =2Ω) are wired in series in a DC circuit. What is the equivalent resistance?
As for series combination of resistances
Equivalent resistance, R = R1 + R2 = 3 + 2 = 5 ohm.

For an electronics project you have three resistors R1, R2, and R3. Unfortunately, only R1 = 3Ω is labeled. Luckily, you paid attention in your physics lectures and you recall the mathematical relationships of (three) resistors in a series circuit and in a parallel circuit. When all three resistors are connected in parallel you measure the total resistance Rparallel = 4 3Ω, and you find a total resistance of Rseries = 13Ω when they are connected in series. a) First,...
. In circuit A, two resistors R1 and R2 are connected in series. In circuit B, two identical resistors are connected in parallel. Both circuits are powered by identical energy sources and include no other resistors. In which circuit, if any, is the current greater across R1?
Two resistors, R1 and R2, are connected in series. a) calculate the single resistance equivalent (in Ω) to the series combination. b) Repeat the calculation for a parallel combination of R1 and R2. (Enter your answer in Ω.)
A. Draw the complex circuit described below A 12 volt emf source connected in series with R1 (3Ω) , in series R1 there are R2 (2Ω) and lamp 1 (4Ω) which are in parallel with each other. Connected in series with that parallel loop is another parallel loop, which includes on one branch , R3 (5Ω), R4 (2Ω) and Lamp 2 (3Ω) in series, and on the other branch of this parallel loop is R5 (7Ω), After that parallel branch...

help You are given a battery (DC power), two resistors (R1 and R2), one DC voltmeter and one DC ammeter. Draw a diagram for the two cases, clearly label the connections of the ammeter and voltmeter. R1 and R2 are connected in series. Use the voltmeter to measure the voltage of R1 and use the ammeter to measure the current. R1 and R2 are connected in parallel. Use the voltmeter to measure the voltage of R1 and use the ammeter...
What is the equivalent resistance of a the following 3 resistors: R1 = 13 Ohms R2 = = 4 Ohms R3 = 42 Ohms In this circuit, R1 and R3 are connected in parallel, and then connected to R2 in series, as shown below: Ri 0--R2- R3
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...
Two identical resistors, R1 and R2, are connected in parallel, and this parallel combination is then connected in series with a 100 Ω resistor, R3 as shown below If the total resistance of the circuit is 300 Ω what must be the resistance of R1 and R2? If the circuit is connected to a 30V battery, what would the current through R1? What voltage is a dropped across R3? 100 S
