Hello everyone,
I am trying to learn about electrical circuits for a physics class.
I have attached a drawing of a circuit related to my question. The battery is 9 volts and each resistor has a 3 ohm resistance.
I need to figure out the resistance through the middle resistor.
The answer is stating it is 3 amps to the left, but I need help understanding this.
Is this circuit considered a parallel curcuit?
If so, the voltage should be shared between branches correct?
Looking at the battery, the positive charge is on the left and the negative charge is on the right correct?
Does the current start flowing from the positive charge? I thought I read that somewhere.
Under these assumptions, I think the current is flowing from the battery left and upwards until it gets to the first branch. There I think there is a voltage drop (split in two) so it looks like 6 volts are going across the left resistor. Then, I would assume the voltage is split in two between the first and second resistor at that branch, so I am thinking 3 volts are across resistor two.
Voltage = Current X Resistance
So if the resistance is 3 ohms and the voltage is 3 volts, then wouldn't that make the current 1 ampere across the 2nd resistor? By my assumptions, it looks like current would be flowing to the right as well and the answer says to the left.
I am really confused about this problem. I have put some serious thought into it. So I would appreciate if anybody can help me with this.
Thanks in advance.
