Understanding Primary and Secondary Cells

What is a key characteristic of primary cells?

• They can be recharged multiple times.

• They are only used in industrial applications.

• They are non-rechargeable.

• They are used in solar panels.

Which type of cell can convert electrical energy back into chemical energy?

• Secondary cells

• Fuel cells

• Solar cells

• Primary cells

In a primary cell, what happens to the chemical energy?

• It is used to power solar panels.

• It remains as chemical energy.

• It is converted to electrical energy and cannot be reversed.

• It is converted to electrical energy and can be reversed.

How are electrons pushed during the recharging of secondary cells?

• From positive to negative by attraction.

• From negative to positive by an external voltage.

• From positive to negative by an external voltage.

• From negative to positive by attraction.

What is the direction of conventional current in a recharging secondary cell?

• It flows in a circular path

• It does not flow

• From negative to positive

• From positive to negative
