Cells can achieve this charge separation by allowing charged ions to flow in and out through the membrane.

What is Ohm’s law theory?

Ohm’s law states that the current I in a resistor is proportional to the potential difference V across it, provided that the temperature of the object is constant. In. equation form, it says. where the proportionality constant R is the resistance of the device .

What is electricity in simple words?

Electricity is the presence and flow of electric charge. Using electricity we can transfer energy in ways that allow us to do simple chores. Its best-known form is the flow of electrons through conductors such as copper wires. The word “electricity” is sometimes used to mean “electrical energy“.
