HI,I need a help in below:
A resistor, R, is connected in series with an inductor, L. An a.c. current, 𝑖, flows through this RL
combination, causing a voltage (𝑉𝑅) of 30V to be developed across the resistor, and a voltage (𝑉𝐿)
of 40V to be developed across the inductor.
Assuming that 𝑉𝑅 is in-phase with 𝑖, and 𝑉𝐿 leads 𝑉𝑅 by 90𝑜, draw a vector diagram for this
arrangement and then calculate the magnitude of the resultant voltage across the whole RL
combination
