2 cards from this section. Quick, good the night before a test.
What happens to the current in a series circuit?
Think about how electricity flows through connected devices.
How do you calculate the total resistance in a series circuit?
Remember the phrase 'add them up!'
What is the total resistance when two resistors of 2Ω and 3Ω are connected in series?
Remember to add resistances in series.
True or False: In a series circuit, the current varies through each resistor.
Consider how electricity flows through each component.
A circuit contains three resistors (5Ω, 10Ω, and 15Ω) connected in series. If a total voltage of 30V is applied, determine the voltage drop across each resistor.
Calculate total resistance and current before finding the voltage across individual resistors.
In a series circuit containing a light bulb (resistance 60Ω) and a heater (resistance 240Ω) connected to a 48V supply, what current flows, and what is the voltage drop across each component?
Find total resistance first, then use Ohm's Law.
