• 1-In a 4.5V cell, there are three lamps are grouped

• 2-In a series circuit, the current leaving the dry cell is:

If the three identical lamps are grouped in parallel with the dry cell of 2V for each lamp, then the voltage across the dry cell is:r

The dry cell sends 0.2A to the two lamps are connected in series to it, then the current for each lamp is:

-The law of the uniqueness of current means:

If the two lamps are grouped in parallel with the dry cell, then:

The law used for this relation UPN = U1=U2 called:

If the voltage of the dry cell is 6V then, the voltage across the closed switch is:

If the dry cell sends 2A, then the current of an open switch is:

The direction of flow of current comes from
