Question

In Lab 02 you have measured the voltage V across the battery and the current I in the circuit when different number of identical bulbs were connected to the same battery in series.

a) Impossible to tell because the current in circuit 2 will be different through each of the light bulbs

b) I1 < I2

c) I1 > I2

d) The relation between the currents I1 and I2 depends on the value of bulb's resistance I1 = I2

e) The relation between the currents I1 and I2 depends on the value of the battery voltage

Explanation / Answer

Option C is correct

I = V/R

as in circuit 2 two bulbs are connected in series so total resistance become 2R

SO,

I2 = I1/2
