Current, Voltage and Resistance, Part 2 (13 pts)

Your name - first and last

Learning Goals:

As you change the value of the battery voltage, how does this change the current through the circuit and the resistance of the resistor?

If the current or resistance remains constant, why do you think?

As you change the value of the resistance of the resistor, how does this change the current through the circuit and the battery voltage? If the current or voltage remains constant, why do you think?

Use understanding to make predictions about a circuit with lights and batteries.

Explore to develop your own ideas about how resistance, current, and battery voltage are related. Write a brief summary below.

M/C Question:

What happens to the current when the voltage is increased in the circuit?

• The current decreases.

• The current increases.

• The current stays the same.

M/C Question:

What happens to the current when the resistance is increased while keeping the voltage constant?

• The current decreases.

• The current stays the same.

• The resistance stops affecting the current.

M/C Question:

What happens to the current when the resistance is decreased and the voltage is kept constant?

• The current decreases.

• The current stays the same.

• The current increases.

M/C Question:

What happens to the current if both the voltage is increased and the resistance is decreased?

• The current stays the same.

• The current decreases.

• The current increases.

M/C Question:
