Circuits Physics

What kind of circuit is this?

• series

• parallel

When all parts of the circuit are connected it is a ______ circuit. 

• open

• closed

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 voltage of a circuit with 4 ohms of resistance and 3 amps of current?

• 12 V

• 21 V

• 4/3 V

• 3/4 V

A student connects a length of unknown material in series with a battery and an ammeter (which measures current flow). When the circuit is complete, the ammeter reads that no current is flowing. The unknown material is most likely ​ ​ (a)  

• an insulator

• a conductor

• a superconductor

• a semiconductor
