Answer:
4
Explanation:
lets say jack has 2 apples and jhon has 2
you add them together then you get 4
It also has to work with other systems in order to make laws
Answer:
The answer is D. Technician B only
Explanation:
First we need to assume they are talking about simple circuits, with the source and a resistor, at zero frequency .If the resistor is left open at a parallel circuit, current will still flow through the other components.
Technician A is incorrect.
Technician B applies Ohm's law,
V = I*R,
V is the voltage
I is the current
R is the resistance
If R remains constant, If the voltage decreases, the current will decrease too
