Measuring Current in Series Circuits Grade 6

What is the unit of measurement for current?

• Volts

• Ohms

• Watts

• Amperes (A)

In a series circuit, how does the current flow through the components?

• The current flows in a random pattern through the components

• The current flows sequentially through each component in a series circuit.

• The current flows simultaneously through all components in a series circuit

• The current flows in the opposite direction through each component in a series circuit

How can you measure the current in a series circuit?

• Place an ammeter in series with the circuit components.

• Place a capacitor in series to measure the current.

• Use an ohmmeter to measure the current directly.

• Connect a voltmeter in parallel with the circuit components.

If you have a series circuit with three light bulbs and one of them burns out, what happens to the current in the circuit?

• The current increases in the circuit.

• The current remains the same in the circuit.

• The current decreases in the circuit.

• The current in the circuit stops flowing.

What instrument is commonly used to measure current in a circuit?

• Multimeter

• Oscilloscope

• Voltmeter

• Thermometer

If you have a series circuit with a resistor and a light bulb, which component will have more current flowing through it?

• Neither

• Resistor

• Both equally

• Light bulb

What happens to the total current in a series circuit if you add another battery in series?

• Decreases

• Becomes negative

• Remains the same

• Increases

Explain why the current is the same at all points in a series circuit.

• The current is the same at all points in a series circuit because the resistance varies at different points.

• The current is the same at all points in a series circuit because there is only one path for the current to flow.

• The current is the same at all points in a series circuit because the components are connected in parallel.

• The current is the same at all points in a series circuit because the voltage is constant throughout.

What is the formula to calculate current in a circuit?

• I = V * R

• I = R / V

• I = V + R

• I = V / R

Why is it important to measure current in a circuit?

• To make the circuit more colorful

• To attract lightning strikes

• To confuse the electrons

• To ensure components are within limits, troubleshoot issues, and calculate power consumption.
