Alternating Current

Question

Wired Faculty App

In an a.c. circuit the voltage applied is E = E₀ sinπt. The resulting current in the circuit is I = I₀ sin $open parentheses ωt space minus space straight pi over 2 close parentheses$ .The power consumption in the circuit is given by

$straight P space equals space fraction numerator straight E subscript 0 straight I subscript 0 over denominator square root of 2 end fraction$

P = zero

$straight P space equals fraction numerator straight E subscript 0 straight I subscript 0 over denominator 2 end fraction$
$straight P space equals space square root of 2 straight E subscript 0 straight I subscript 0$

Solution

B.

P = zero
