3 cards from this section. Quick, good the night before a test.
Define work done in a circuit using the correct formula.
Think about the relationship between voltage and charge.
What does the letter 'I' represent in the context of electric circuits?
It is measured in Amperes.
What is the formula for calculating work done in a circuit?
Think about how voltage and charge interaction leads to energy transfer.
True or False: Current is the measure of energy transferred in a circuit.
Focus on the definitions of current and work.
A circuit with a voltage of 12 volts and a current of 4 Amperes runs for 10 seconds. Calculate the total work done. How can reducing the voltage impact the work done?
Remember to multiply all the components.
If an appliance uses 1500 Watts and operates for 2 hours, determine the total charge that has passed through if the supply voltage is 120 volts.
Convert hours into seconds to use the right time unit.
