What did you find out about the current at different places in parallel circuit?

Kirchhoff said that the sum of the currents leaving are the same as the current that entered. The current in any parallel branch depends on Ohms law. The voltage across the device divided by its' resistance equals the current.

What do you find out about the current at different places in the series circuit?
The current at different places in a series circuit is the same. Kirchoff's current law states that the signed sum of the currents entering a node is zero. A consequence of this is that the current at every point in a series circuit is the same.
How does the location of the circuit compare to the current at other places in the circuit in a simple circuit?
Reading this question, one kind of has to guess what's being asked. Here's a statementthat may or may not be helpful to the questioner:A series circuit is one in which there's never a point where the current has to decidewhich path to take. There's never a point where the current can split, and there's onlyone possible route all the way through the circuit.In a series circuit, the magnitude of the current is the same at every point.
What does a ampermetre do in a circuit?
Spelt: AmmeterIt measures the current flowing around the circuit. In different places in the circuit, the reading may be higher or lower.
In a series circuit how does the current differ at different places along that circuit?
In a series circuit, current will remain the same through all elements, and the voltage drop across elements will vary. So the answer is: it doesn't.
Why does parallel circuit have higher current than the series?
Parallel branches each draw a current from the supply. The more branches, the more current is drawn. Adding additional loads to a series circuit increases its resistance, causing its supply current to reduce.
What are the disadvantages of using a parallel circuit?
What is arguably the major disadvantage of a parallel circuit is that as you add more and more things in parallel, the current draw on the source goes up and up and up. If the source cannot supply the current that is "demanded" by the devices all strapped across the so-called "rails" of the circuit, the voltage will (must!) decrease. This could be very bad, as some devices, notably motors, don't like to run at low voltage and can actually be damaged if voltage sags too much and they don't have undervoltage protection. Fortunately, we have a pretty good power grid in many places, and this isn't a problem. Additionally, many devices have undervoltage protection built in, and they'll "trip" and shut down if voltages sag to a preset threshold.
What is the Function of fuse in an electric circuit?
A fuse places a limit on the amount of current that can be drawn by an electric circuit by opening (blowing or melting) when the current exceeds a preset limit. This protects the circuit and the surroundings from fire or damage in the case of an overload or short circuit.
How can you determine that two walls of a building are parallel?
Measure the distance at different places. If the walls are parallel, then the distance will be the same.
What is the difference between simultaneous and parallel events?
Parallel events are similar events. Simultaneous events are events that occur at the same time. Both simultaneous and parallel events occur at different places.

Why is voltmeter connected in parallel and ammeter connected in series in a circuit?
An ideal voltmeter has infinite impedance(resistance). If you were to break the circuit and put it in series and try to make a measurement, it is easy to see that the circuit would act completely differently and your measurement would be wrong. An ideal ammeter is always connected in series because it has 0 resistance, so all of the current would flow through it, and not through the wire that you are trying to measure the current of.A better answer though is to think about what you are trying to measure. When you say something is 3 Volts, that is a difference between the voltages at two different points. If you want to see what the voltage drop across a resistor is, for example, you need to put one probe of the voltmeter on one side of the resistor and the other probe on the other side of the resistor. That setup is simply called being in parallel.Voltage is potential difference between two points, hence measured across or in parallel, where as current is measured in series since current flows (*)
