An era is a commonly used word for a long period of time. When used in science, for example geology, an era denotes a clearly defined period of time of arbitrary but well-defined length, such as for example the Mesozoic Era from 252 Maâ66 Ma, delimited by a start event and an end event.
As you increase voltage to the muscle describe how it responds to the increased stimulus. As the voltage was increased from threshold to maximum voltage, there was a greater force in the muscle contraction. Once the maximum voltage (2500 mv) was reached, even if there was an increase in voltage, the force of the muscle contraction remained the same.
When wired in series, you take the individual voltage (1.2V in this case) and multiply that by the number of cells in the pack (6) to get the total pack nominal voltage. If you do the math, youâll see that a 6-cell pack has a total nominal voltage of 7.2 volts.
