You can measure across *any* component - see the answer on measuring voltage.

For any resistance measurement, be SURE that:

1. The circuit is disconnected from the power supply, and

2. "Energy storage" components such as capacitors are discharged.

If the circuit does contain capacitors of reasonable size (microfarads or more) these may demand some power from the meter to charge them, so you can get an artificially low reading at first, but it will rise to the correct value as the capacitors charge.

An indispensable first step would have to be to find a clear definition of what is

meant by a "parallel series circuit", as no such configuration is taken up in standard

engineering texts.

Not sure what you are getting at, but you always measure voltage "across" a load of some type. When you are measuring a battery that is connected to nothing, the load is essentially the meter. To measure current you have to either have an amp-meter in series with the load; or use a clamp-on meter around a single wire that is passing current. With a clamp-on you are reading the flowing current by induction.

In a parallel circuit does the battery run out very quickly?

No, it will run out just as much as if you put it in a series circuit. Parallel circuits involve the same voltage or amperage to go to each component.


If Three 12 volt batteries are connected in parallel what is the effect on the circuit?

There will be no effect on the voltage. That is the effective voltage will be only 12 volt. But there will be increase of current.


Compare and contrast series and parallel circuits?

In a series circuit, there is only one path for the current to flow through. In a parallel circuit, there are multiple paths for the current to flow through. For example, most old Christmas lights are series circuits. If one light in the whole strand of lights went out, then all the lights would go out. This is because once one resistance is out, the circuit is no longer complete, so the current can not flow. An example of a parallel circuit could be your household lighting. When you turn on your kitchen lights, your bathroom lights don't turn on with it, do they? That is because it is a parallel circuit. In a parallel circuit, there are multiple paths for the current. It doesn't matter if one light is on and another is off because the current can go through another way. In a series circuit as you increase resistance, the voltage and current decrease. In a parallel circuit, as you increase resistance, the voltage and current increase. Think of a series circuit as a one-lane road. The car would be the current, the gas in the car would the voltage, and the traffic lights would be the resistance. Since you are on a one-lane road, as you keep stopping at traffic lights, you aren't going very fast or far. Now, think of parallel circuits as a multi-lane road (or highway). The car is the current, the gas in the car is the voltage, and the traffic lights (or closed roads, or accidents, anything that would slow you down on the road) are the resistance. When you are driving and one road is closed, you don't have to stop because you can continue driving and go on a different road to reach your destination.


How does a voltage divider work?

The essential circuit of a voltage divider, also called a potential divider, is:


Can inserting a resistor in a circuit have an effect similar to an open circuit?

If the resistance is large enough, then there might not be enough voltage difference to allow much current. Since, Voltage = Current * Resistance, if resistance goes really large, and your voltage doesn't change, your current must decrease. An open circuit is where you do not have any current flowing, so whether no current verses very little current is the same is up to you.

What will happen to voltage in a parallel circuit?

In a parallel circuit the voltage across each component is the same.


What is the voltage drop running through the parallel potion of the circuit?

A: There is no voltage drop running through in a parallel circuit but rather the voltage drop across each branch of a parallel circuit is the same


Why a voltage only in parallel?

Depends on what circuit you're refering to, a parallel circuit has parallel lines because it allows for voltage to pass through the circuit, giving more power.


How much voltage does each branch of a parallel circuit?

Yes. The voltage across every branch of a parallel circuit is the same. (It may not be the supply voltage, if there's another component between the power supply and either or both ends of the parallel circuit.)

What type of circuit has the same voltage drop across each of its components?

A parallel circuit. Since a parallel circuit has only two nodes, there can be only one voltage difference between the nodes.


Is the current the same everywhere in the parallel circuit?

No. The current in a series circuit is the same everywhere. The voltage across a parallel circuit is the same.
