A cell whose internal resistance is 0.55\(\Omega\) delivers a current of 4 A to an external resistor. What is the lost voltage of the cell?
Correct Option:
B
The lost voltage (V_lost) in a cell is calculated using the formula:
V_lost = I * r
where:
* I is the current flowing through the cell.
* r is the internal resistance of the cell.
Given:
* I = 4 A
* r = 0.55 Ω
Therefore,
V_lost = 4 A * 0.55 Ω = 2.20 V
