I been studying my ARRL Ham radio license manual. I'm having trouble with remembering the electric parts like voltage, ohm, current, amps etc. is there a easy way to remember these? thanks

sort of what i did replacing the E I and R with what they stand forThere are a lot of different formulas, but many are just the same equation stated differently. So learn just one of each of the variations.
Someone used voltage (E) equals current (I) times resistance (R) earlier; or E= IR. So that can tell you E/I = R or E/R = I.
Do the same thing for power; P = E times I or ......
Are there specific equations you are having trouble with?
E = electromotive force or voltage, not V.V..voltage
I = current in amps.C...Current
umm noE = electromotive force or voltage, not V.
I = current in amps.
how would you go about finding correct answear.
How much power is being used in a circuit when the voltage is 120 volts DC and the current is 2.5 amperes?
1440 watts.
300 watts
48 watts
30 watts
As in post #4, P=IEhow would you go about finding correct answear.

What formula is used to calculate current in a circuit?
Current (I) equals voltage (E) multiplied by resistance (R).
Current (I) equals voltage (E) divided by resistance (R).
Current (I) equals voltage (E) added to resistance (R).
Current (I) equals voltage (E) minus resistance (R).
I have trouble remembering formulas like this. thanks
With this question here you can eliminate 2 answers right off the bat. You will never add or subtract anything to fiqure out the answer.
Why does everything have to be easy??I been studying my ARRL Ham radio license manual. I'm having trouble with remembering the electric parts like voltage, ohm, current, amps etc. is there a easy way to remember these? thanks
