The current I in the adjoining circuit is

Options

A. `1/45 A`
B. `1/15 A`
C. `1/10 A`
D. `1/5 A`

Answer

C

Explanation

Equivalent resistance R of the circuit is given as :
`1/R = 1/30 + (1)/((30 + 30)) = 1/30 + 1/30 rArr R = 20Omega`
` therefore ` Circuit current `I= V/R = (2V)/(20Omega ) = 1/10A`
