Question

According to Ohm's law, if the current is constant:

A. if R increases, V must also increase.
B. V can decrease, but only if R increases.
C. if R increases, V must decrease.
D. both V and R must remain constant.

Answer 1

V=IR
I=k
V=kR

A.) because V is in direct relation to R.

Answer 2

Ohm's law: V=I * R

if I is constant you can ignore it for this question then V = R

if R increases, V must also increase, so the answer is A

Answer 3

hint:
using the Ohm's law, we see thta the subsequent ratio:
\[\huge \frac{{\Delta V}}{R} = {\text{constant}}\]
has to be a constant value
So, what can you conclude?

Answer 4

oops.. we see that*...
