Thanks Shooter.
Now, I more confused.
I'm a visual person on some things and this is one of them.
It's when the test question might ask for: How much wattage is used with a .05 resistor to give you 3 amps with 120 volts? You know, these kind of questions that I'll never use with a handy-talkie, but are answers needed to pass the test. Then later on they might have same question on test, but 120 volts is changed around to 30 watts, how much current is needed to give you 10 amps. These are not the actual questions on test.

Well tech test wont mix the 2 formulas together. It will ask questions that each formula independently can answer. For example:
T5D01 (B)
What formula is used to calculate current in a circuit?
A. Current (I) equals voltage (E) multiplied by resistance (R)
B. Current (I) equals voltage (E) divided by resistance (R)
C. Current (I) equals voltage (E) added to resistance (R)
D. Current (I) equals voltage (E) minus resistance (R)
Remeber EARs, and E is first in division..
amps or current=voltage/resistance.
T5D02 (A)
What formula is used to calculate voltage in a circuit?
A. Voltage (E) equals current (I) multiplied by resistance (R)
B. Voltage (E) equals current (I) divided by resistance (R)
C. Voltage (E) equals current (I) added to resistance (R)
D. Voltage (E) equals current (I) minus resistance (R)
EARs again...
Voltage=amps*resistance
T5D03 (B)
What formula is used to calculate resistance in a circuit?
A. Resistance (R) equals voltage (E) multiplied by current (I)
B. Resistance (R) equals voltage (E) divided by current (I)
C. Resistance (R) equals voltage (E) added to current (I)
D. Resistance (R) equals voltage (E) minus current (I)
EARs and E is always first. Resistance=voltage/ amps or current
T5D04 (B)
What is the resistance of a circuit in which a current of 3 amperes flows through a resistor connected to 90 volts?
A. 3 ohms
B. 30 ohms
C. 93 ohms
D. 270 ohms
EARs, R=E/A, R=90/3
All you gotta remember is that EAR is the equation. And E is first in division. There wont be any questions that will ask about power in relation to resistance because those are more complex and require square roots and powers. The test is required to be completable without a calculator. Start tossing in square roots and powers with just pencil and paper, and Im def out. They will ask power equations which are PIE, and they will have ohms law questions, EAR.A and I are current or amps in either equation.
From here, its in sections t5d and t5c
Tech test questions If my way of recalling is confusing, you can try and memorize them seperate. I had to recall them and their relationship to each other and this is how I did it, by only remebering 1 formula, for both equations.
