What is the primary goal when dealing with combination circuits?

• To separate all series components

• To decrease the current

• To combine all parallel components into one number

• To increase the voltage

In a complex circuit, what is a node?

• A point where two or more components meet

• A measurement of voltage

• A type of circuit

• A type of resistor

What is the first step in solving combination circuits?

• Reduce the parallel circuits

• Measure the current

• Calculate the total power

• Solve the series circuit first

How do you calculate the total resistance in a series circuit?

• By dividing all resistances

What is the total resistance of a circuit with resistors of 1 ohm, 1.18 ohms, and 3 ohms in series?

• 3.18 ohms

• 6.18 ohms

• 4.18 ohms

• 5.18 ohms

What is the formula to calculate current in a circuit?

• Resistance multiplied by current

• Voltage multiplied by resistance

• Resistance divided by voltage

• Voltage divided by resistance

In a series circuit, how does the voltage drop across each resistor?

• It decreases

• It increases

• It remains constant

• It fluctuates randomly

What is the power formula used in the example?

• P = R / I

• P = I^2 * R

• P = V^2 / R
