How are the dry cells connected in series connection?
The voltage will be double that of one dry cell. The current will be that of one dry cell.
What will happen if more bulbs are added to a circuit with one cell?
YESAnswerNot necessarily. The current depends on the potential difference and the load resistance. If you connect cells in parallel, you do not effect its voltage or the load, so the current is unaffected (although the battery's current 'capacity' will increase). If you connect the cells in series, then you will increase the voltage and the current will increase.
Can you measure the internal resistance of dry cell using multimeter?
Well, you do use a multimeter to measure it, but not directly. You need at least one other thing besides the multimeter and the dry cell. Here's a simple way to do it: -- Take a resistor. With the meter set to measure resistance, measure the resistor's value. Call that 'R'. -- With the meter set to measure voltage, measure the voltage of the dry cell. Call it 'V1'. -- Connect the resistor across the dry cell. Measure the dry cell's voltage again. Call it 'V2 ' this time . V2 will be less than V1 . The internal resistance of the dry cell is R times (V1 - V2) / V2
Is the emf of a cell equal to the total potential drop in the external circuit of the cell?
The EMF of a cell is the voltage across the terminals at zero current. This is the quoted cell voltage but as soon as a current is dawn from the cell, the voltage will drop. It's due to the internal resistance of the cell. In a circuit diagram, a cell is often shown as a voltage source (a perfect source) and a resistor in series to represent the internal resistance. Using Ohms Law, it can be seen that as soon as a current flows, a voltage will be developed across the internal resistance, so reducing the voltage that is seen at the terminals of the cell. The higher the current draw, the higher the voltage drop inside the cell. Normally, the voltage drop is minimal but in most cells, as it loses charge, the internal resistance rises. Eventually it will reach the point where most of the voltage is dropped across the internal resistance, leaving little to drive the intended load. Often, if a battery is removed from a device and measured, the voltage will be measured as equal to or very close to the quoted cell voltage. It is easy to make a judgment that a battery is good when it is almost dead. The only way to confirm the state of the battery is to measure the voltage at the terminals while the load is attached. The results can be very different to the off load voltage. Alkaline cells have a low internal resistance compared to other dry cells. This makes them well suited for high current drain applications. The internal resistance also rises more slowly than most other cells, so they remain useful far longer than zinc-carbon types.
What is meant by a cell has a voltage of 1.5volt?
No. The potential DIFFERENCE of a battery (or, more accurately, a dry cell) is 1.5 V.
How are the dry cells connected in series connection?
The voltage will be double that of one dry cell. The current will be that of one dry cell.
What is the voltage of a dry cell in a torch battery called?
The cell voltage.
What will happen if more bulbs are added to a circuit with one cell?
YESAnswerNot necessarily. The current depends on the potential difference and the load resistance. If you connect cells in parallel, you do not effect its voltage or the load, so the current is unaffected (although the battery's current 'capacity' will increase). If you connect the cells in series, then you will increase the voltage and the current will increase.
Can the current supplied by a dry cell give an electric shock?
no. if the cell is dry, the electric capacity also becomes dry and this does not affect the conductor.

What kind current is produced by a dry cell?
A dry cell battery does not use current it produces a current when connected to an electrical load. The type of current that the dry cell produces is DC (direct current).
How does the voltage measured across a dry cell ompare with the voltage drop measured across three bulbs in series?
