Question

In a parallel circuit with a 12 V battery and three 6 Ohm resistors, what is the total current in the entire circuit? Select one:a.36 Ampsb.6 Ampsc.4 Ampsd.2 Amps

Answer 1

First, let's find the equivalent resistance. Since they are in parallel, we can find it as follows:

`\begin{gathered} (1)/(R_(eq))=(1)/(R1)+(1)/(R2)+(1)/(R3) \\ so: \\ (1)/(R_(eq))=(1)/(6)+(1)/(6)+(1)/(6)=(1)/(2) \\ Hence: \\ R_(eq)=2\Omega \end{gathered}`

Now, we can use ohm's law to calculate the current:

`\begin{gathered} V=IR \\ so: \\ I=(V)/(R)=(12)/(2)=6 \end{gathered}`

Answer:

b.

6 Amps
