Resistance
Complete the Ohm's Law expression:
Resistance = Voltage / ?????
Current
How can you improve RELIABILITY in an investigation?
By repeating the investigation (multiple trials)

In a Series circuit, the current before a 10 Ohm light bulb is measured at 5 Amps. What would be the current measurement after the light bulb?
5 Amps
(Current in a series circuit does not change)
Resistance causes electrical energy to be converted to other forms. Electrical energy would be converted into which main form of energy in an electric fan?
Kinetic (Movement)
If a more precise instrument is used to get measurements in an investigation, what is being improved?
Accuracy

Snap his fingers
If an attacking team kick the ball past the dead-ball line, how does play restart?
20m restart
The voltage provided by a battery in a parallel circuit is 10 Volts. What voltage would be measured across a bulb in each branch of this circuit? (There is only one bulb in each branch, and there are 5 branches)
10 Volts
(Voltage in each branch of a parallel circuit is equal to the voltage provided by the power source)
As the thickness of a wire increases, the resistance decreases. What type of relationship is this?
Inversely Proportional
A student wants to know how different types of light bulbs affects the current flowing in an electrical circuit. What would be the dependent variable in this investigation?
The current in the circuit.
In 'Guardians of the Galaxy', who is Gamora's sister?
Nebula
Between 2000 and 2002, the 'Northern Eagles' played in the NRL. This was a merged team made from the North Sydney Bears and which other current team?
Manly Sea-Eagles
In a Series Circuit, there are 4 light bulbs. I the voltage supplied to the circuit is 20V, how much voltage would be measured across each bulb?
5 V
(Voltage is split between the bulbs)
Knowing that R = V/I, what would be the Voltage across a device that had resistance of 100 Ohms and a Current of 0.5 Amps?
50 Volts
An experiment is designed to test an hypothesis that copper wires are better conductors than aluminium wires. Give two conditions in this investigation which will need to be constant for it to be a VALID investigation.
Same Thickness
Same Length
Same Circuit (Voltage and/or Current)
Which Marvel film did Scarlett Johansson first appear, in her role as 'Black Widow'?
Iron Man II
Which Australian NRL team has never won a premiership?
Gold Coast Titans
In a parallel circuit, a power source is providing 20V and the total current is 2.4 A. If there are 4 branches which are drawing equal current, what would be the current in each branch?
0.6 A
