A car battery has ________ resistance than a dry cell.
a car battery of 12V provides a current of about 200A, which is the current needed to operate a starter motor. So a battery has a very small internal resistance.
also,The cause of non-correctable battery problems and.A weak cell holds less capacity and is discharged more quickly.
The internal resistance of a battery cannot be measured with a conventional multimeter
Electromotive force is a
emf is measured in
Under what condition, the current drawn from the cell is maximum?
Internal resistance of cell when there is current of 0.40 A when a battery of 6.0 V is connected to a resistor of 13.5 Ω is
Two terminals of a cell of emf 2.5 V are connected to the two ends of the 10 ohm resistance coil. If the current in the circuit is 0.2 A, then the internal resistance of the cell is
The internal resistance of the cell can be obtained from the relation,
Current provided by a battery is maximum when
What is the maximum current that can be drawn from a cell of emf E and internal resistance r connected to an external resistance R?
as the maximum current that can be drawn from a cell is for R =0 therefore, it is I = E/r.
The term open circuit means
An open circuit implies that the two terminals are points that are externally disconnected, which is equivalent to a resistance R=∞ . This means that zero current can flow between the two terminals, regardless of any voltage difference.
