If R₁

Question

If R₁ < R₂ < R₃,and if these resistors are connected in series in a circuit,which one dissipates the greatest power? A)R₁ B)R₂ C)R₃ D)All are equal in power dissipation.

Quizplus · Accepted Answer

The power dissipated in a resistor is given by P=I^2R, where I is the current flowing through the resistor and R is the resistance of the resistor. Since all three resistors are in series, the current flowing through each resistor is the same. Therefore, the resistor with the highest resistance (R₃) will dissipate the greatest power as P=I^2R and the resistance (R) is the highest.
