Question

Solve the following question:
In an electric circuit, two resistors of 12 0 each are joined in parallel to a 6 V battery. Find the current drawn from the battery.

Answer 1

Let net resistance of the given parallel combination be R_net, Then 

`1/"R"_"net"=1/12+1/12`

`1/"R"_"net"= 2/12=1/6`

⇒ R_net = 6 Ω
Hence, current, `"i"="V"/"R"_"net"=(6"V")/(6 Ω)=1"A"`.
