Practice Problems

A resistor is connected to a 9 volt supply. How much work will be done by the supply if coulombs flow through the resistor?Joules

It takes Joules to move coulombs through a circuit. What is the potential difference applied to the circuit? Volts

How much charge can be moved through a potential difference of volts by 50 Joules of energy? Coulombs

A circuit consists of a battery, a switch, several wires and a lamp. The total length of the circuit is 2.5 meters. What is the current in the circuit if it takes minutes for a single coulomb to make a complete trip through the circuit? Amperes

How many coulombs will pass through a 10 amp circuit in minutes?
