Three resistors each having value 'R' are connected as shown in figure. What is the equivalent resistance between 'X' and 'Y'?

Correct answer: A. 3R

  • A. 3R
  • B. R
  • C. R/3
  • D. R3

Explanation

The resistors are connected in a series so the final resistance between x and y would be the sum of all resistances, R+R+R=3R.

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.
