Answer:
3/8
Step-by-step explanation:
Answer:
The voltage across resistor is 
Step-by-step explanation:
We are given with Voltage across terminals of a series RL circuit, 
And Resistance R=40Ω
And inductor reactance
Ω
Since Resistor and inductor are in series, same current flows through both.
And that current, I = 

= 
Therefore voltage across resistor, 
Answer:
No solution
Step-by-step explanation:
n+7=n+3
First subtract n to the other side:
n-n+7=n-n+3
7=3
No solution
