4 cards from this section. Quick, good the night before a test.
What is the formula for electrical current?
Think of charge and time.
In what units is voltage measured?
What is electric potential difference's unit?
What is the standard unit of power in electrical circuits?
What is used to describe energy use per unit time?
True or False: In a series circuit, the voltage is the same across all components.
Consider how voltage behaves in series compared to parallel.
A series circuit has three resistors: R1 = 2Ω, R2 = 3Ω, and R3 = 5Ω, with an applied voltage of 12V. Calculate the total power consumed by the circuit.
Calculate total resistance first, then find current and finally power.
If a parallel circuit contains a 10Ω and a 5Ω resistor, what is the current flowing if 20V is supplied across the circuit?
Use the formula for equivalent resistance in parallel circuits.
