SSC JE EE: Basic Electrical and Network Theory Booster Quiz -9

The voltage and current equation can be expanded as

v(t) = 4 + 5 sin (ωt) + 10 sin (3ωt - 30°) V

i(t) = 3 + 6 sin (ωt + 60°) + 12 sin (3ωt + 30°) A

The average power will be:

What will be the cross-sectional area (in sq. m) of an 18 m long cylindrical wire when the resistivity of the wire is 0.67 ohm-meter and the resistance of the wire is 12 ohms?

What is the power factor of the circuit when a current of 8A flows in the circuit when 100V DC is applied to it whereas it takes 125V AC to produce the same current?

Which of the following statement as CORRECT?
