Question 469: AC fundamentals

Question

An ac voltage is applied to a resistance R and an inductor L in series.  If R and the inductive reactance are both equal to 3 $$\Omega $$, the phase difference between the applied voltage and the current in the circuit is

Accepted Answer

tan $$\phi $$ = $${{{X_L}} \over R}$$ = $${3 \over 3}$$ = 1
$$ \Rightarrow $$ $$\phi $$ = 45
