Practicals Flashcards
1
Q
What is it important to do in the electric circuit required practical?
A
- record the length of the wire accurately
- measure and observe the potential difference and current
- use appropriate apparatus and methods to measure current and potential difference to work out the resistance
2
Q
What is the 1st part of the method for the electric circuit practical?
A
To connect the circuit then to Connect the crocodile clips to the resistance wire, 100cm apart
3
Q
Resistance is current over voltage, True or False
A
False, it’s Voltage divided by current
4
Q
In the density practical, what is it important to do?
A
- record the mass accurately
- measure and observe the mass and the volume of the different objects
- use appropriate apparatus and methods to measure volume and mass
5
Q
What is the aim of the density practical?
A
To measure the density of various materials with the eureka can
6
Q
What is the aim of the electric circuit practical?
A
To investigate how changing the length of the wire affects its resistance
7
Q
How do you calculate the volume of a cube in the density practical?
A
Length x Width x Height
