Hi there, @LittleHeron! ^-^

For Q1:
Taken from wiki "Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field."

For Q2:
A car bettery has a greater difference in electric potential energy.
A 12V battery produces more current than a 1.5V battery produces,
through the same device, because the potential difference between
the terminals of the 12V battery is 8 times the potential difference
between the terminals of the 1.5V battery.

For Q3:
Taken from wiki, again, "The SI unit for measuring an electric current is the ampere, which is the flow of electric charge across a surface at the rate of one coulomb per second. Electric current is measured using a device called an ammeter..

Next time, please post these questions in the physics section, and try to post one question at a time. Thanks! ^-^
