Answer 1

A capacitor and resistor are connected with an AC source as shown in figure. Reactance of capacitor is X_C = 3 Ω and resistance of resistor is 4 Ω. Phase difference between current I and I₁ is approx 53.

Explanation:

I₁ = `"V"_0/4`sin t

I₂ = `"V"_0/3`sin t `(pi/2+"t")`

tan θ = `4/3`

θ = 53°
