When 10 cells of emf 10v are connected in parallel total emf is
Answers
The total emf is 10V.
Explanation:
- Let the equivalent total emf be E.
- Given that the cells which are 10 in number are connected in parallel combination and the emf across them is 10V.
- We know that, Ohm's law states that, V=IR where V is the potential, I is the current and R is the resistance of a resistor. When the case of potential difference across a resistor arrives, Ohm's law gives, I=ΔV/R, where ΔV is the potential difference of the resistor.
- Since for the 10 cells which are in parallel combination, potential difference that is 10V is same for all resistors, the total emf will also be 10V, that is, it will be same for all cells.
Hence, the total emf is 10V.

Answer: The total emf is 10V
Explanation: Let E be the corresponding total emf.
Given that there are ten cells linked in parallel and that the emf across them is ten volts.
Ohm's law says that V=IR, where V is the potential, I is the current, and R is the resistive resistance of a resistor. When the scenario of potential difference across a resistor arises, Ohm's law states that I=V/R, where V is the resistor's potential difference.
Because the potential difference of 10V is the same for all resistors in the 10 cells in parallel arrangement, the total emf will be the same for all cells.
As a result, the overall emf is 10V.
