When your friends from Exercise 15 plug a large home entertainment system into the outlet, it doesn't work properly because the voltage rise provided by the extra outlet is only 60 V. The power company provides a voltage rise of 120 V, so where is the missing voltage ?

Voltage loss is due to use of thin connection wires.

Explanation:

-According to Ohm's Law, voltage is proportional to current.

-The voltage drop in each wire is proportional to the current.

-The more current (or charges per second )you try sending  the harder it is.

-Hence, electrostatic energy is lost on the way which results in voltage loss.

because if the tool that you are using is not balanced it there would be false mass.
