Answer:

the voltage across the resistor is V= 0

Explanation:

The correct answer is zero.

The answer is zero because the inductor acts as open circuit.

$i= i_0[1-e^{-\frac{t}{\tau} }]$

i_o= maximum current

\tau= L/R= time constant

i= current at any instant

$V= V_0[1-e^{-\frac{t}{\tau} }]$

at t=0 at the moment when contact is made

V=V_o[1-1]

⇒V= 0 V
