Three light bulbs each of resistance 25 ohms are connected ina parallel circuit and connects to a 9.0volt battery to complete the circuit. What is the voltage across each resistor!

Answer #1

Since the bulbs are connected in parallel, voltage will be same in every bulb, which is 9 V.
Since the resistors are in parallel, 1/R = 1/R1 + 1/R1 + 1/R1 = 3/R1
Where R is the net resistance of the circuit and R1 is the resistance of the the individual bulb.
R = R1/3 = 25/3.
The current in the circuit = V/R = 9/(25/3) = 1.08 A
Since all the resistors are the same, current through each resistor = 1.08/3 = 0.36 A
Voltage across each resistor = 0.36 x R1
= 0.36 x 25
= 9 V
