Combo Circuit Quiz

Which circuit rules apply in combo circuits?

• Series
• Parallel
• Both Series and Parallel
• Neither Series nor Parallel

Simplifying a complex circuit by redrawing parallel components to equivalent components in a series is a common strategy for solving individual resistance and current for each resistor.

• True
• False

Which steps should be included in solving a combination circuit total current?

• Assess which resistors in a circuit are connected together in simple series or simple parallel.
• Re-draw the circuit, replacing each series or parallel resistor combinations with a single, equivalent-value resistor
• Repeat until the entire circuit is reduced to one equivalent resistor, or all in a series.
• Calculate total current from total voltage and total resistance

Which statement best describes resistors R1 and R2 in relation to each other?

• The resistors are considered in series with each other so their current will be the same for both
• The resistors are considered in parallel with each other so their current will be the same for both
• The resistors are considered in parallel with each other so their voltage will be the same for both
• The resistors are considered in series with each other so their voltage will be the same for both

Which statement is not true about resistor 3?

• The current of resistor 3 will be the same as the current running through the resistance equivalent of resistor 1 and 2.
• Resistor 3 is considered in a series with the resistance equivalence of resistors 1 and 2.
• Resistor 3 will have the same voltage drop as the other two resistors in parallel.
