Question

In the computer lab, two tables each had 5 light bulbs connected. On table 1, the lightbulbs were connected in parallel. What happened when the first lightbulb was disconnected? What happened when the first lightbulb of the set on table, which were connected in series was disconnected? Are the two circuits shown below equivalent? Prove or disproved by showing your calculation for the equivalent resistance. Determine the equivalent resistance (R_eq), voltages (V_1 and V_2), currents (I_b and I_1 and I_2), and powers (Power_batteries, P_light bulb 1 and P_light bulb 2). Which bulb would be the brightest? Assume that the total voltage from the batteries = 12 V and each light bulb has a 100 Ohm resistance.

Explanation / Answer

here,

5)

when the light bulbs are coonected in parallel

and the first bulb is diconnected

then the current will flow thorugh the circuit and just the equivalent resistance is increased

when the light bulbs are coonected in series

and the first bulb is diconnected

then the current will not flow thorugh the circuit because the circuit is not complete
