Answer:
The answer to your question is given below.
Explanation:
From the diagram given in the question, we can see that the bulbs are in parallel connection. This implies that different current will go through the bulb but the same voltage. But the resistance of each bulb is the same, therefore the same current current will go through them.
This can further be understood if we determine the current flowing through each bulb. This is illustrated below:
Voltage (V) = 30V
Resistant 1 (R1) = 15Ω
Current 1 (I1) =..?
V = I1R1
30 = I1 x 15
Divide both side by 15
I1 = 30/15
I1 = 2A.
Voltage (V) = 30V
Resistant 2 (R2) = 15Ω
Current 2 (I2) =..?
V = I2R2
30 = I2 x 15
Divide both side by 15
I2 = 30/15
I2 = 2A.
The overall current(I) in the circuit:
I = I1 + I2
I = 2 + 2 = 4A.
From the illustrations above, we can see that the same current will flow through each bulb as the will current split into two equal parts
