why voltage is different in series combination?even when the source of voltage cell or battery is common.
Answers
Answer:
In a series circuit, the current is the same at each resistor. ... The voltage drop (I•R) will be the same for each resistor since the current at and the resistance of each resistor is the same.
A voltage source is any pair of points between which an electrical potential difference exists.
This potential difference can be constant, varying slowly or in a periodic cycle. It can be huge or really tiny.
A somewhat constant voltage source is often called a ‘direct current’ (DC) voltage source. Generally, if one terminal is always higher in potential than the other, then it is a DC voltage source.
If the voltage (difference in potentials) keeps reversing a particular number of times per second, then it is an Alternating Crrent (AC). The number of times per second here is called frequency and is measured in a very simple unit called Hertz. Typically, the frequency of power supply is 50 Hz (in Europe, India etc.) and 60 Hz in (USA etc.).
Voltage sources can be power supply terminals on a wall outlet or a phone charger or an electric train overhead power line. They can also be very tiny signal sources from small sensors, in which case, we use those signal as information, but not power.
In deeper Electrical Engineering, the meaning of voltage source may be in contrast with another kind of electrical source known as Current Source. The difference is that, regardless of the load , in Voltage source, the available voltage is somewhat constant all the time whereas in current source, the available current is constant all the time.
Now, a battery is an arrangement to make a power supply voltage source available. It is most often made of a chemical system where electrical energy is stored as ion imbalance within some chemical solutions that can be consumed as and when required. The ‘cells’ which together constitute a battery have specific voltage values particular to the nature of their chemistry. (eg. Lead Acid batteries have a cell voltage of 2Volts). Combining many cells in series or parallel, a battery is constructed to the required higher voltages and power ratings.

Answer:
In a series circuit, the current is the same at each resistor. ... The voltage drop (I•R) will be the same for each resistor since the current at and the resistance of each resistor is the same. Thus the electric potential difference across any one of the bulbs will be the same as that across any one of the other bulbs.
