2 cards from this section. Quick, good the night before a test.
What is the total resistance of a 6Ω and 12Ω resistor in parallel?
Use the formula \\( \\frac{1}{R_{total}} = \\frac{1}{6} + \\frac{1}{12} \\).
If two resistors of 5Ω and 10Ω are in parallel, what voltage is the same across each if the source voltage is 20V?
In parallel, voltage is the same.
What happens to total resistance when resistors are connected in parallel?
Remember the formula for total resistance.
In a parallel circuit, if the voltage across each resistor is the same, what varies?
Focus on Ohm's law.
A circuit contains three parallel resistors: 10Ω, 20Ω, and 30Ω. If a voltage of 60V is applied, calculate the total current supplied by the source.
Calculate total resistance first using the parallel formula.
Discuss how adding more resistors in parallel affects the overall current draw of a circuit and provide an example with calculations.
Use the parallel formula to assess how current changes.
