4 cards from this section. Quick, good the night before a test.
What is the formula for electric current?
Remember what the terms Q and t stand for.
What unit measures resistance?
Think of what opposes the flow of electricity.
What is the formula for calculating electric current?
Remember 'I' represents current.
True or False: In a parallel circuit, the voltage across each component is different.
Think about how connections are structured.
A circuit has a voltage of 15 volts and a total resistance of 3 ohms. Calculate the current and power consumed by the circuit.
Remember the formulas for both current and power.
Design a circuit including a battery, two resistors (5 ohms and 10 ohms) in series, and determine the total resistance and current if the battery provides 20 volts.
Add resistance values and use Ohm's Law.
