Solver the all parts of given question:
Question: A battery with an emf of 12.0 V shows a terminal voltae of 11.8 V when operating a circuit with four light bulbs each rated at 4 W (at 12.0 V) which are connected in parellel.
Part A: draw a diagram of the arrangement?
Part B: what is the total external resistance of this circuit?
Part C: what is the current in each bulb?
Part D: What is the internal resistance of the battery?
This is a physic question, reply as soon as possible. Thank you.
