. A 2-V cell is connected to a 1-12 resistor. How many electrons come out of the negative terminal of thecell in 2 minutes? |
| Answer» ACCORDING to Ohm’s law, the current in the circuit would be:I = V/R =2/1 = 1 AThe amount of CHARGE transferred when the current flows for 2 minutes is GIVEN as ,Q = I*t = 2 * 2 * 60s = 240CTotal number of electrons coming out of the battery/cell would be,n= 240 * 6.242×10^18 = 14.98 * 10^20 electrons | |
