Question

A 5-ohm resistor is connected to a 1.5 V battery. The 5-ohm resistor is replaced with a smaller resistor. In order to keep the current through the resistor the same, what should be done to the voltage of the battery

(A) Increase it

(B) Decrease it

(C) Keep it the same

Explain why

Answer 1

Below

Step-by-step explanation:

V = IR

V/R = I

Now you can see that if you decrease R, you will need to decrease V to have the same value of I
