1. If there is a current of 10 amperes in a circuit for 10 minutes, what quantity of electric charge flows in through the circuit? 2. How much current must there be in a circuit if 100 coulombs flow past a point in the circuit in 4 seconds? 3. How much time is required for 10 coulombs of charge to flow past a point if the rate of flow

To use Coulomb’s Law equation to algebraically solve for an unknown quantity (F, d, Q1 or Q2) in a physics word problem. To combine Coulomb’s Law equation with Newton’s second law, free-body diagrams and trigonometric functions to analyze physical situations that include interacting charges.
Charge of any ordinary matter is quantized in integral multiples of e. An electron carries one unit of negative charge, −e, while a proton carries one unit of positive charge, +e. In a closed system, the total amount of charge is conserved since charge can neither be created nor destroyed.
The three basic principles for this tutorial can be explained using electrons, or more specifically, the charge they create: Voltage is the difference in charge between two points. Current is the rate at which charge is flowing. Resistance is a material's tendency to resist the flow of charge (current).
Your task: rank the fixed charges from most negative to most positive. Warning: this is not as easy as it first seems. Encourage students to do numerous test runs before doing the ranking! Includes a pdf worksheet. Physlet Physics: Charging Objects and Static Cling
Calculate the charge on the 1000 μF capacitor. The 1000 μF capacitor is connected across an uncharged 500 μF capacitor by closing the switch S. The charge initially stored by the 1000 μF capacitor is now shared with the 500 μF capacitor. Calculate the total capacitance of the capacitors in parallel.
