Three resistors of resistance R1, R2, and R3 are connected as shown in the figure.The equivalent resistance is:

Correct answer: E. None of the above

  • A. Option A
  • B. Option B
  • C. Option C
  • D. Option D
  • E. None of the above

Explanation

(All options are wrong) R2 and R3 are connected in parallel, so their total resistances would be RT=(R2R3)/(R2+R3). And then R1 is connected in series so the equivalence resistance would be the sum of R1 and the total resistance in the parallel resistors, which would be R1+((R2R3)/(R2+R3)) which equals to (R1R2+R2R3+R3R1)/(R2+R3).

About Current Electricity

Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
