In the given L-R circuit, which of the following gives correct relation between V,`V_(R) and V`?

Options

A. `V lt V_(R)+V_(L)`
B. `V gt V_(R)+V_(L)``
C. `V=V_(R)+V_(L)`
D. none of these

Answer

A

Explanation

`e=sqrt(e_(R)^(2)+e_(L)^(2))`
`V=sqrt(V_(R)^(2)+V_(L)^(2))`
In series circuit due to voltage magnification voltage across L and voltage across R is greater than applied voltage.
`therefore V lt V_(R) +V_(L)`.
