Which one of the following is the value of current I in the circuit shown above?

Options

A. `5 A`
B. `10 A`
C. `15 A`
D. `20 A`

Answer

C

Explanation

Given circuit shows the parallel combination of resistance.
Hence equivalent resistance `=(1)/(R)=(1)/(R_(1))+(1)/(R_(2))`
`implies" "(1)/(R)=(1)/(1)+(1)/(2)" ":." "R=(2)/(3)Omega`
According to Ohm's V=IR
`:." "I=(V)/(R)=(10xx3)/(2)=15A`
