Question

The power used by an electric tool can be determined by multiplying the _____.

Answer 1

Power can be expressed by the product of current and voltage.  To see this, consider the units of current and voltage:

$[I]= \frac{C}{s} \\ \\ {[V]=\frac{J}{C}} \\ \\ {[V*I]=\frac{C}{s}\frac{J}{C}=\frac{J}{s}=W}$

Where C is coulombs (charge), s is seconds, J is joules (energy), and W is Watts, or power.  See that watts are Joules per second, or the time rate of change of energy.

Answer 2

Answer:

current time the voltage. Hope this helps:-)
