The current in the circuit shown in figure 7 below, will be:

A

`1//45A`

B

`1//15A`

C

`1//10A`

D

`1//5A`

Text Solution

Verified by Experts

The correct Answer is:
C
`R_(s) =60+60 =120Omega`
`R_(s) and R_(3)=60Omega` connected in parallel
`R_(p) =(R_(s)R_(3))/(R_(s) +R_(3)) =(120 xx 60)/( 120+60) =(120 xx 60)/(180) =40Omega`
`i =(V)/(R ) =(4)/(40) =(1)/(10)A`
