What is the difference between objects that use electricity from power stations and those that use electricity from batteries?
Technically, you are speaking about the delivery of current. Electricity is one type of current. The current has two differences: The current from batteries has a much lower voltage, and it is DC, while the electricity from the electrical plug is AC. Devices that use current have to be adapted to these two situations. Some devices are only battery powered, e.g. flashlight. Other devices have internal mechanisms to switch the power current between battery and electrical outlet, e.g. a laptop.
P-n junction diode?
A PN Junction Diode is one of the least complex Semiconductor Devices around, and which has the normal for passing current in one and only heading just. Be that as it may, dissimilar to a resistor, a diode does not carry on directly regarding the connected voltage as the diode has an exponential current-voltage ( I-V ) relationship and thusly we can not portrayed its operation by just utilizing a comparison. ex: Ohm's law.
How the cells of same emf can be connected to get large value of emf?
They are connected in 'series', the negative terminal of one cell connected to the positive terminal of the next cell, and so on with as many cells as you have, so that there is only one path for current through the entire combination of cells. In this configuration, the EMF of the combination is the sum of the individual EMFs, but the combination can't deliver any more current (amperes) than any single cell can.
Series circuits and parallel circuits how do they differ?
Components connected in series are connected along a single path, so the same current flows through all of the components.Components connected in parallel are connected so the same voltage is applied to each component
How do electric generators convert kinetic energy into electrical energy?
They revolve sets of coils of wire across a strong magnetic field, and this induces electrical currents in the coils. NB The current will only flow if thetwo ends of the coils are connected, and this is achieved by whatever circuit is connected to the generator's output.
How shunt helps to extend the range of ammeter?
A shunt is connected in parallel with an ammeter. Any current applied to parallel devices will divide betwen them, so the ammeter will pass only a part of the total current.
What topology can only have a maximum of 20 devices connected to it?
it is the bus
What is unipolar electronic devices?
the unipolar devices are those which conducts the current in one direction only or in which the current flow due to majority carriers only
Why is the current source connected in series only?
Current sources should not be connected in series. It's okay to connect them in parallel.
Does a resistor only decrease current in a circuit?
A resistor does not only decrease current in a circuit it can also reduce tension(voltage) if connected in series.
Why pmmc used for DC only?
Because in the coil DC current follow easly and pmmc meter is making with coil and AC current is not follow in coil so we used the pmmc only fpr DC current.
Is there any current at the input port of a ups if it is not connected to the main supply and the ups is on?
No, not at all. It will have current when it is charging only
How many peripheral devices can be connected to a single USB port?
On a typical setup, only one device can be connected to the ports. However, if you have a special USB port, or a device that will split a USB port, you can connect 2 or more devices.
Alternating currents travels in only one direction and is the type of current that most electronic devices require including computers?
Alternating currents travels in only one direction and is the type of current that most electronic devices require including computers?
How do you explain the effect of the number of batteries on the amount of current produced?
The number of batteries has only an effect on the amount of current when they are equivalent and connected in parallel. The amount of current that can flow from a group of batteries connected in series is limited to the current provided by the battery that produces the lowest current flow in the string.
Alternating current travels in only one direction and is typre of current that most electronic devices require including computers?
True ~tekno
Are most computers consisting of many computers and are usually connected by a networking devices such as a hub switch or access point?
Most computers today consist of many processors. Most business computers are connected via hub/switch/access point. Most broadband home users are connected to an access point, only fraction of current home computers use a hub/switch.
