Electricity

Question 1

definiton of an electrical current

Answer 1

it is the rate of flow of charge

Question 2

whats the equation that links charge, current and time also name what each letter stands for

Answer 2

Q= I X t

Q=charge
T= time
I= current

Question 3

the triangle that links charge current and time

Answer 3

Q
I T

Question 4

whats the equation for potential difference,

Answer 4

V= E DIVIDED BY Q

V= potential difference
E= energy transfered
Q= charge

Question 5

triangle for potential difference

Answer 5

E
V Q

Question 6

What is the difference between a series and a parallel circuit

Answer 6

-a series circuit has only one path for the current to flow
-a parallel circuit has more than one

Question 7

what is the Ohm’s law?

Answer 7

the current through an ohmic conduction (at a constant temperature) is directly proportional to the potential difference across the resistor.

Question 8

what happens to the resistance of a filament lamp as the temperature increases

Answer 8

as the temperature increases, the resistance also does

Question 9

What happens to the resistance of a thermistor as it increases in temperature?

Answer 9

The resistance decreases as the temperature increases.

Question 10

What happens to potential difference in series/parallel circuits?

Answer 10

Potential difference is the same on different paths of a parallel circuit; it splits across components in a series circuit.
