What is the Condition for terminal voltage across a secondary cell to be equal to its emf?
The condition for the terminal voltage across a secondary cell to be equal to its emf is when there is no current flowing through the cell. When there is no current, there is no voltage drop across the internal resistance of the cell, and thus the terminal voltage equals the emf.
What is current drawn by pencil cell of 1.5 v?
nothing..............
What is the maximum current in zinc carbon dry cell?
The maximum current output for a zinc-carbon dry cell is typically around 1 ampere. However, this can vary depending on the specific brand and size of the cell. It is important to check the manufacturer's specifications for accurate information.
What is the v-i characteristics of solar cell?
The V-I (voltage-current) characteristics of a solar cell show the relationship between the voltage applied across the cell and the current generated by the cell. At zero voltage, a solar cell generates its maximum current (short-circuit current), while at zero current, the cell generates its maximum voltage (open-circuit voltage). The V-I curve gives an insight into the performance and behavior of the solar cell under different operating conditions.
How does internal resistance affect operation of a cell or battery?
It causes the battery's voltage to drop when a current is drawn from it.
Disadvantage on Daniell cell?
A disadvantage of the gravity cell is that a current has to be continually drawn to keep the two solutions from mixing by diffusion, so it is unsuitable for intermittent use.
What is open post voltage?
The open post voltage in electronics is the maximum voltage available from a solar cell. This will occur at zero current.
What is the maximum condition in a single excel 2003 cell can have?
In versions earlier than 2007 you can only have 3 conditions in one cell. You'll have to use VBA to go beyond those three.
What about Isc short circuit current of solar cell?
Solar panels are rated very strange. Isc is current short circuit. The voltage is Eoc, or voltage open circuit. The two are multiplied to get the power rating of the panel under max sun. Problems here include: 1. Max sun is rare (2 to 5 hours a day is considered a normal "sun day") 2. You can not ever reach the current of short and voltage open condition. A typical 100 watt panel may supply 76 watts at full sunlight. That means you will see 152 to 300 watts a day from a 100 watt panel. Hardly being honest.
What is cell rim in Excel?
You may mean the gridlines that visually define a cell, or borders that can be drawn around a cell.
The voltage or current capacity of a battery can be increased if two or more cells are connected together To increase current capacity a series connection is used?
Each cell of a battery has a predefined voltage, and for a given type of battery, a predefined maximum current capability. Putting cells in series, just like putting batteries in series, increases the voltage (1 AAA battery = 1.5 volts, 2 AAA batteries in series = 3 volts). Putting cells in parallel increases the amount of current that can be drawn from them (1 cell = 1 cell max. current, 2 cells in parallel = 2 cells worth max current). Note available power will be the same (P = V*I), so whether you use a series or parallel connection usually depends upon the desired output voltage.
What kind current is produced by a dry cell?
A dry cell produces direct current (DC) when a chemical reaction within the cell generates a flow of electrons in one direction. This current flows from the negative terminal to the positive terminal of the cell.
