Consider the circuit shown in the figure. Take R1=2R , R2=R and R3=R , find the magnitude of the current passing through the resistor R2 in terms on V/R . Express your answer using one decimal place.
Added by James M.
Step 1
Since R1 and R2 are in series, their resistances add up, so the total resistance of that part of the circuit is 2R + R = 3R. This 3R is in parallel with R3, so the total resistance of the circuit, Rt, can be found using the formula for resistors in parallel: Show more…
