Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

• Ohm's law is a fundamental law of electrical engineering.

• It states that the current through a conductor is directly proportional to the voltage across it.

• The proportionality constant is the resistance of the conductor.

• The formula for Ohm's law is I = V/R, where I is the current, V is th...read more

The electrolyte used in lead acid battery is sulfuric acid.

• Lead acid batteries use sulfuric acid as the electrolyte.

• The sulfuric acid reacts with the lead plates to produce electricity.

• The concentration of sulfuric acid in the battery determines its voltage.

• The electrolyte level in the battery needs to be checked and topped up regularly.

• Adding distilled water to the battery can help maintain the electrolyte level.
