Y9U1T3 - series and parallel recall

What happens to the total resistance in a series circuit as more resistors are added?

• Increases
• Decreases
• Stays the same
• Depends on the resistors used

In a parallel circuit, how is the total current related to the current through each resistor?

• Total current is divided equally among the resistors
• Total current is the same as individual currents
• Total current decreases as resistors are added
• Total current increases as resistors are added

Which type of circuit provides more than one pathway for current to flow?

• Parallel circuit
• Series circuit
• Complex circuit
• Singular circuit

If one resistor in a parallel circuit fails, what happens to the current in the other branches?

• Decreases
• Increases
• Stays the same
• Becomes zero

Which statement is true about the voltage in a series circuit?

• Voltage remains constant throughout
• Voltage is divided among the resistors
• Voltage increases with each resistor
• Voltage is inversely proportional to resistance

How is the total resistance calculated in a parallel circuit?

• 1/R = 1/R1 + 1/R2

• R = R1 + R2

• Taking the square root of the resistances
• Multiplying the resistances

What happens to the total current in a parallel circuit if a resistor is removed?

• Increases
• Decreases
• Stays the same
• Becomes zero

In a series circuit, what is the same across all components?

• Current
• Voltage
• Resistance
• Power

Why are parallel circuits used in homes for electrical wiring?

• They allow devices to work independently
• They save energy
• They are easier to set up
• They provide higher voltage

What happens to the brightness of bulbs in a parallel circuit if one bulb is removed?

• Other bulbs remain the same, only the removed bulb is affected
• All bulbs become dimmer
• All bulbs become brighter
• All bulbs turn off
