Investigating voltage & current

Voltage is measured in __.

• volts.
• watts.
• coulombs. 

As the resistance of a circuit increases, the current will

• increase

• decrease

• stay the same

• increase and then decrease

Current has units: 

• kilowatt·hour 
• ampere 
• coulomb 
• volt 

How many Volts would it take to push 5 Amps through a resistance of 10 Ohms

• 10 volts

• 1 volt

• 50 volts

• 5 volts

If the current through a circuit is 2 A and the resistance of a light bulb in the circuit is 10 Ohms, what is the voltage difference across the light bulb?

• 5 V
• 12 V
• 0.2 V
• 20 V

A voltmeter should be placed ........... in a circuit

• in parallel
• in series
• in order
• upside down

Resistance is a measure of....

• the energy per unit charge in a circuit
• how hard it is for electrons to move through the circuit
• how hard it is for electrons to move through the battery
• the number of charge carriers in a circuit

What equation links voltage, current and resistance

• V = IR

• V = CR

• V = I/R

• V = R/I

• V = C/R

Which of these is correct for a test circuit

• ammeter in series and voltmeter in parallel

• ammeter in series and voltmeter in series

• ammeter in parallel and voltmeter in parallel

• ammeter in parallel and voltmeter in series

How should you put in an Ammeter?

• In Parallel
• In Series
