Series Circuits and Ohm's Law

What kind of circuit is this?

• series

• parallel

The picture shows an electrical circuit. This circuit is a series circuit because: 

• It has 3 light bulbs.

• The same current flows through all three light bulbs.

• It uses a single battery.

• The electrical current has more than one path to flow through

A correct statement of Ohm’s Law is:

• I= V R

• V ∝ I

• V = IR

• both b and c

What is the unit for resistance?

• volts

• amps

• coulombs

• ohms

What happens to the current in a circuit as the resistance decreases?

• Current increases

• Current Decreases

• Current remains the same

What is the unit for Resistance?

• Ohms

• Volts (V)

• amps (A)

As the resistance of a circuit increases, the current will...

• increase

• decrease

• stay the same

What is the Voltage of a circuit that has a resistance of 5 Ω and a current of 2 A?

• 25 V

• 10 V

• 2.5 V

• 0.4 V

If the battery produced 12.6 Volts and there was a 6 Ohm resistor, what would be the current?

• 2.1 Amps

• 2.4 Amps

• 1.71 Amps

• 15 Amps

This circuit has a 24 volt battery and the resistor is 8 ohms. How many amps are running through the circuit?

• 3 Amps

• 192 Amps

• 2 Amps

• 4 Amps
