Ohms law help?

Question

volts = current x resistance.

lets say amps = 10 and resistance = 1.

10 x 1 = 10volts.

if resistance goes up to 5 ohms

10 x5 = 50

but isnt ohms inversly proportional to volts? so ohms should make volts decrease. help??

Answer 1

Your question is incorrect because Ohms is a unit .

Answer 2

Let's say that...

E = IR

where: E = voltage in volts; I = current in amperes; R = resistance in ohms

If we derive the formula and find R,

R = E/I

Therefore, the resistance(ohms) is inversely proportional to the current(amperes), in which the voltage(volts) is the constant of proportionality.

And so, if the resistance value increases, the value of current decreases, with the constant value of voltage.

If you want to find the relationship between the voltage and the resistance, we can refer to the general formula of the Ohm's Law and we can find that...

...the voltage is directly proportional to the resistance, in which the current is the constant of proportionality.

And so, if the value of voltage increases, the resistance value also increases, with the constant value of current.

Answer 3

If the voltage stays the same then the current will drop

2amps x 5ohms = 10 Volts

For the current to stay at 10 amps the voltage has to be 50V with 5amps resistance.

Answer 4

The law against 'Ohms', as you call them, was changed many years ago.

Come on dude!! this is the 21st century.

Answer 5

If resistance goes up to 5 ohms, your amperage dropped to 2 amps. The voltage usually remains constant.

If you have a 5 ohms resistance on your circuit and want to maintain 10 amps of current draw on it, you're going to have to have 50 volts to do it.

Answer 6

V=IR

if V=kR by definition, then

V varies directly with R

set I=k

so volts are directly proportional to ohms.
