Electrical charge is measured in Coulombs \text{(C)} and current is measured in amperes \text{(A)}. The current can be thought of as the rate of flow of charge around the circuit. You can measure current using an ammeter. You can calculate the charge that has flown around a circuit in a certain time \text{(s)} using the following equation:
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
Coulomb’s Law: Problems and Solutions. Compute the electric force between two charges of 5×10−9 C and −3×10−8 C which are separated by d = 10 cm. Solution: the magnitude of the electrostatic force between two point charges is given by Coulomb’s law as. =.
3. 243.0x10 charges pass a given point in 5 s. Calculate the current in the wire.

Key learning points. Electric charge, Q, is measured in coulombs (C). Electric current is a measure of the rate of flow of electric charge, calculated using: I = Q ÷ t. Potential difference is a measure of the energy transferred by each coulomb of charge, calculated using: V = E ÷ Q.
Electric Charge Calculations. Electric charge is a property of matter where it experiences a force when in an electromagnetic field. The idea behind it is: Fundamental particles can have 0, +1 or −1 electric charge: + and − are pulled towards each other. + pushes + away. − pushes − away. We sum it up by saying:
