Resistor R1 = 6.0 Ω is connected series to a parallel combination of resistors R2 = 4.0 Ω and R3 = 12.0 Ω. What is the voltage across R1 if R3 carries a current of 0.50 A? 12.0 V 6.0 V 2.0 V 3.0 v

Step 1
Given: R2 = 4.0 Ω R3 = 12.0 Ω Using the formula for calculating the total resistance of two resistors in parallel: 1/R_parallel = 1/R2 + 1/R3 1/R_parallel = 1/4 + 1/12 1/R_parallel = 3/12 + 1/12 1/R_parallel = 4/12 R_parallel = 12/4 R_parallel = 3.0 Ω Show more…

Two resistors have resistances $R_{1}$ and $R_{2} .$ When the resistors are connected in series to a $12.0-\mathrm{V}$ battery, the current from the battery is 2.00 A. When the resistors are connected in parallel to the battery, the total current from the battery is 9.00 A. Determine $R_{1}$ and $R_{2}$ .
