- The power in an AC circuit which cannot perform work. It is calculated by the following formula: P = I·V·sinθ, where P is the power in watts, I is the current in amperes, V is the voltage in volts, and sinθ is the sine of the angular phase difference between the current and the voltage. Also called reactive power, idle power, quadrature power, volt-amperes reactive, or reactive volt-amperes.

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
