Question

State two Quantities that are used to determine whether accumulator requires recharging or not

Answer 1

Two quantities that ae used whether accumulator requires charging or not is

• Relative density of the acid

• The voltage output.

Answer 2

Answer:

The answer is,

1. Relative density of the acid

2. Voltage Output

Explanation:

The two Quantities that are used to determine whether the accumulator requires recharging or not are

1. Relative density of acid
2. Voltage output

Relative density of acid:

• Relative density is defined as the ratio of density of the substance to the density of reference material.
• In a fully charged battery to discharged battery the density varies from 1.28 to 1.15
• The relative density should not be allowed to fall below 1.18 of electrolyte in a acid accumulator

Voltage Output:

• The voltage output is defined as the voltage released from the device.
• From the output of the circuit the analog voltage is formed.
