Question

Assume that the batteries and the light bulbs in the circuits are identical. Choose all the the correct statements applied.

Notice: a battery is rated by its capacity of charge in the battery, defined as current * time. Thus, for the same type of batteries, the larger the current it carries, the shorter the life span of the battery.

Question options:

Currents passing the bulbs are different with Ia < Ib < Ic.

Currents passing the bulbs are the same with Ia= Ib = Ic.

Currents passing the bulbs are different with Ia > Ib > Ic.

The battery wired in circuit (a) lasts the longest.

The batteries wired in circuit (c) last the longest.

Currents passing the bulbs are different with Ia < Ib < Ic.

Currents passing the bulbs are the same with Ia= Ib = Ic.

Currents passing the bulbs are different with Ia > Ib > Ic.

The battery wired in circuit (a) lasts the longest.

The batteries wired in circuit (c) last the longest.

Explanation / Answer

V/R=I

If V is high keeping resistance constant then current wil be high so Ia <Ib <Ic as Va <Vb <Vc

The battery wired in circuit (a) lasts the longest as current flows due to it is less
