Sole the all parts of following question:
Question: A light bulb used in a slide projector draws a current of 6 amperes and provides a 20 ohm resistance in a circuit.
Part A: What voltage is supplied to the circuit?
Part B: If two slide projectors are connected in a parallel across the same voltage source, the current drawn from the source is _________. Anything change if the slide projectors are connected in a series? If so, explain.
Part C: If the power consumed by the slide projectors the same in each circuit? If so, what is it? If not, describe any differences.
Please show me step by step or type in formulas used. I am so lost!!
