OHMS Law Flashcards
What is the ohms law formula?
V = I x R
What is the word definition of ohms law?
The current passing through a circuit is proportionate to the voltage over the resistance
How do you calculate voltage?
I x R
(Current x resistance)
How do you calculate current?
V / R
(Voltage divided by resistance)
How do you calculate resistance?
V / C
Voltage divided by current
If the resistance is increased, providing the voltage is the same. What will happen to the current?
It will decrease
If the voltage doubles, what will happen to the current?
It will also double
Why can’t you apply ohms law to AC?
The current is constantly changing and you need to take into consideration other factors such as capacitance and inductance.
Who first explained ohms law?
George ohm. A German physicist.
