Battery

Battery container should be acid resistance therefore it is made up of

• Glass

• Plastic

• Wood

• All of the above

To prevent local action in battery, only ............is used in electrolytes

• Pump water

• Distilled water

• Tap water

• Both A and C

A dead storage battery can be revived by

• Adding distilled water

• Adding so-called battery restorer

• A dose of H₂SO₄

• None of the above

Cell short circuit results in

• Low specific gravity electrolyte

• Abnormal high-temperature

• Reduced gassing on charge

• All of the above

If the battery is wrongly connected on charge following will happen

• Current delivered by the battery will be high

• Current drawing will be Nil

• Currently drawing will be very small

• Currently drawing will be very high

What is the function of the electrolyte in a battery?

• Acts as a medium for the transfer of charge between the anode and cathode

• Stores excess energy

• Regulates the temperature of the battery

• Provides structural support

What is the primary function of the anode in a battery during operation?

• Storing excess energy

• Accepting electrons released at the cathode

• Releasing electrons

• Regulating the voltage

What are the factors that affect the performance of a battery

• Intrinsic properties of anode, cathode

    and electrolyte materials used

• Compression energy to the battery

• Engineering involved in designing

    and fabricating the battery

• Contamination in the materials
