Solve the following questions:
Question I: A flashlight bulb carries a current of 0.18A for 77s.
Part A: How much charge flows through the bulb in this time?
Part B: How many electrons?
Question II: When a potential difference of 12 V is applied to a wire 7.2m long and 0.31mm in diameter the result is an electric current of 2.2A.
Part A: What is the resistivity of the wire?
Please show me step by step or type in formulas used. I am so lost!!
