Currents in Multi-Loop Circuits

EANDM-ALPY3M

Consider the circuit in the accompanying diagram. Two resistors are connected to a battery which has a voltage $V$. There is a current of$1\,A$ flowing through the $5\Omega$ resistor in the right leg.

What is the voltage $V$ on the battery, and what is the value of the current $I_{left} $ flowing through the $10\Omega$ resistor in the left leg?

A

$V=5\,V$; $I_{left}=1 \,A$

B

$V=3.33V$; $I_{left}=0.33 \,A$

C

$V=5\,V$; $I_{left}=1/2 \,A$

D

$V=15\,V$; $I_{left}=3/2 \,A$
