Very basic current direction question

In summary, the conversation discusses the calculation of the capacitance on each plate and the resulting value of 500 microfarads. The speakers also mention the connection between the rightmost part of the two right capacitors and the presence of four capacitors in parallel. They debate whether the current can flow through both pairs of capacitors or only one, and the concept of equivalent capacitance is also brought up.

I attached a picture..Im just curious, if your calculating the capacitance on each plate why is the answer .5 if the V=1000 and each capacitor plate is 500 microfarads..

If C=500 for each plate then first you have two sets of parallel plates so it simples to a series with two plates of 1000 microfarads..which simplifies to 1/1000+1/1000=2/1000, so the capacitance is 500. C=Q/V,

5x10^-6=Q/1000, shouldn't Q=5? Thanks

Your attachment appears to be missing a connection to the rightmost part of the two right caps.

But assuming that there is meant to be a connection there, then you have basically 4 caps in parallel, with the way the voltage source is shown connected.
 
  • #4
Yes they are supposed to be connected...so once you combine the parallel sets on either side and reduce it to two capacitors are those capacitors in parallel or series
 
  • #5
The current has a choice of where to go
 
  • #6
So it only flows through one pair of the capacitors, not both?
 
  • #7
It can flow to both. Its just the matter of finding one equivalent capacitance now. Since you reduced the four parallel caps to two equivalent caps (one on each side), the current can go to either cap. When a current has more than one path to go, those components are in...?
 

Related to Very basic current direction question

What is current direction?

Current direction refers to the direction in which electric charge flows in a circuit. It is typically described in terms of either conventional current flow, which assumes that current flows from positive to negative, or electron current flow, which describes the movement of electrons from negative to positive.

What factors affect current direction?

The direction of current flow is primarily determined by the direction of the electric field in a circuit. In addition, the type of material used in the circuit, such as a conductor or a semiconductor, can also affect the direction of current flow.

How is current direction measured?

Current direction can be measured using a variety of instruments, such as ammeters, which measure the amount of current flowing through a circuit, or voltmeters, which measure the voltage difference between two points in a circuit. The direction of current flow can also be indicated by the polarity of a battery or power source in a circuit.

Can current direction change?

Yes, the direction of current flow can change depending on the type of circuit and the components within it. For example, in an alternating current (AC) circuit, the direction of current flow changes periodically, while in a direct current (DC) circuit, the direction remains constant.

Why is understanding current direction important?

Understanding current direction is important for designing and troubleshooting electrical circuits. It allows scientists and engineers to predict how components will behave in a circuit and to identify any potential issues that may arise due to incorrect current direction.
