Battery Arrest

A single battery cell.

• creates a potential between two electrodes

• stores chemicals that make electricity

• has a voltage of 1.2V to 1.5V in most cases

• all of the above

A 12V carbon zinc battery:

• is 8 cells connected in a series circuit

• is 12 cells connected in parallel

• is 8 cells connected in a parallel

• is one 12V cell

If you draw 0.2A from a 6A-H battery, how long will it take to run down?

• 25 Hours

• 30 Hours

• 17 Hours

• 8 Hours

If you connect eight 1.5, 300mA-h in a series, what will the total voltage and amp-hour rating?

• 9v, 300mA-H

• 1.5v, 1.8A-H

• 18v,1.5A-H

• 12v, 300mA-H

If you connect 8 1.5v, 100mA-H batteries in parallel, what will be the total voltage and amp-hour rating?

• 9V, 300mA-h

• 1.5v 800mA-h

• 18v 1.5Ah

• 6v 450mA

What should be done with a carbon-zinc battery that has run down.

• Recharge it

• Remove because acid might leak

What cell type can put out more than 3 volts?

• lead-acid

• NiMH

• Li-ion

• Alkaline

For a given size which cell type stores the most energy

• Li-Ion

• ni-cad

• alkaline

• carbon-zinc

A secondary battery can be recharged

• true

• false
