Question

14. Figure below shows three identical bulbs in a circuit. What happens to the brightness of disconnect the bulb B? A. Bulb C gets brighter B. Bulb C gets dimmer C. Bulb C's brightness does not change D. Bulb C goes out. 5. Resistors Ri-1 ohm and R2 3ohm are connected in parallel. If heat is produced at a ra in the resistor Ri, then in 3.00 ohm resistor it is produced at a rate of, A. 8.00 W B. 25.0 w C. 73.0 W D. 113 W E. None of above. R, I-10A 16. A 12 V battery(e) with internal resistance of 1ohm is connected with several light bulbs figure below. The resistance of each bulb is 1ohm. Calculate the current in the circuit A. 3.5 A B. 4.6 A C. 5.2 A 7.1 A R C R A

Explanation / Answer

14) OPTION C . The current through the bulb C remains the same, even if you disconnect it. hence the bubl would not change its brightness.

15) Using the equation, POWER, P = I2R.
The current through R1 can be found out.
The reamining current would flow through R2. i.e. I2 = 10 - I1
Power dissipated through R2 = (I2)2 R2
