What is the current through a component measured with?
An ammeter
1 of 6
Where do you place an ammeter on a circuit?
In series with the component
2 of 6
What is the potential difference of a component measured with?
Parallel to the component
3 of 6
What does OHMS law state?
The current through a resistor at a constant temperature is directly proportional to the potential difference across the resistor
4 of 6
How do you work out the Potential different (v)
V= W/Q or E/Q W is the work done; Q is the charge in coulombs; E is energy transferred in Joules
5 of 6
How do you work out the resistance (R)
R = V/I V is The potential difference; I is the current in amps
