Lesson 10 Do Now

Which of the following components is NOT typically used in constructing a parallel circuit?

• Resistor

• Capacitor

• Inductor

• Transformer

What happens to the total current in a parallel circuit when more branches are added?

• It decreases

• It remains the same

• It increases

• It becomes zero

In a parallel circuit, the voltage across each branch is:

• Different for each branch

• The same as the total voltage

• Half of the total voltage

• Zero

Which instrument is used to measure the current flowing through a branch in a parallel circuit?

• Voltmeter

• Ammeter

• Ohmmeter

• Galvanometer

How should a voltmeter be connected in a parallel circuit to measure the voltage across a component?

• In series with the component

• In parallel with the component

• At the power source

• It cannot be connected

If a parallel circuit has three resistors with values 6 Ω, 3 Ω, and 2 Ω, what is the total resistance?

• 1 Ω

• 11 Ω

• 0.92 Ω

• 1.09 Ω

What is the main advantage of using a parallel circuit over a series circuit?

• Lower total resistance

• Higher total resistance

• Components share the same current

• Components share the same voltage

In a parallel circuit, if one branch is disconnected, what happens to the other branches?

• They stop working

• They continue to work

• They short circuit

• They increase in resistance

Which of the following is true about the current in a parallel circuit?

• It is the same through all branches

• It divides among the branches

• It is zero in all branches

• It is double in all branches
