According to ohm’s law, which combination of units is the same as the unit for resistance?

volt ÷ ampere
ampere × volt
volt + ampere
ampere ÷ volt

option A)

volt ÷ ampere

Step-by-step explanation:

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points the constant of proportionality, where resistance is constant.

I = V / R

rearranging it in terms of R will give

R = V / I

V- voltage is measured in volts

I - current is measured in ampere

So,

ohm  = volts / ampere

or

ohms = volt ÷ ampere

The right choice is volt ÷ ampere

According to Ohms's Law

V = I * R

Solving for R we get

R = V / I

The units of quantities is Resistance = Volts / Ampere

So option A is the correct answer

d

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
