The direction of electric current

In terms of circuit analysis, we normally consider the direction of electric current from positive to negative. Mathematically, negative charge flowing in one direction is equivalent to positive charges flowing in the opposite direction.

Fascinating Tomato Electricity Battery Experiment for Kids

Kids are always impressed when you can use common household produce to produce electricity. This spin on the classic potato clock or lemon battery uses a juicy, red TOMATO! In this amazing tomato battery your …

In a dc circuit the direction of current inside the battery and …

Direction of current through a circuit with multiple batteries

The sign of the current is showing the direction of the current relative to the arrow, you painted on the schematics. If the flow of the current (btw: Electrons always flow against the direction of …

Module 4 Electric Current-The Battery | Science 111

The voltage of a battery is synonymous with its electromotive force, or emf. This force is responsible for the flow of charge through the circuit, known as the electric current. Key …

Fruit Battery

The amount of current depends on the size of electrode and the surface of electrode in contact with fruit. You must use larger electrodes to produce higher current. The other solution is to connect 3 apples in parallel. This may work if …
