4 cards from this section. Quick, good the night before a test.
What is an electric circuit?
Think about what components are needed for current to travel.
Define voltage in your own words.
Relate it to pressure in a water pipe.
What does a battery provide in a circuit?
Think about the source of energy in the circuit.
True or False: A closed circuit allows current to flow.
Consider what happens when you open a light switch.
A circuit contains a 12V battery, a resistor of 6Ω, and a light bulb rated for 50W. Calculate the current flowing in the circuit and determine if the bulb will operate safely.
Remember Ohm's Law and how power relates to current.
Design a circuit with two resistors in series of 4Ω and 6Ω connected to a 10V battery. Calculate the total resistance and the current in the circuit.
Consider how total resistance is affected in a series circuit.
