In the giren circuit Ab.ced and four lamps Connect
ed with a battery of bor.
bo
AA
cor- What kind of combination are the lamps arranged in?
(0) which lamp glow the brightest ?
What is the resistance of Bulb c ?
?
What is voltage alross bulb A ​

Answer 1

Explanation:

The lamps are in parallel. <br> Advantages: <br> If one lamp is faulty, it will not affect the working of the other lamps. They will also be using the full potential of the battery as they are connected in parallel. <br> The lamp with the highest power will glow the brightest. <br> P=VI <br> In this case, all the bulbs have the same voltage. But lamp C has the highest current. Hence, for Lamp C P=5 x 60 Watt = 300 W. (the maximum). <br> The total current in the circuit = 3+ 4 + 5 + 3 = 15 A <br> The Voltage = 60 V <br> V = IR and hence R = V/I <br> = 60/15 A = 4A <br> V= IR and hence R = V/I <br> = 60/15 A = 4A <br>
