What is Ohm's law? (in less than 30 words)?

Question

please don't use too much technical language, make it plain and simple for me to understand please.

Answer 1

Voltage is directly proportional to current

Answer 2

Ohm's law describes the relationship between the three most fundamental quantities in circuit theory: voltage, current, and resistance. To talk about Ohm's law, even in plain language, you really need to choose one of these three quantities, and then explain how it relates to the other two. This is really it in a nut shell.

For example, if I choose current, then I might say that as resistance (to the flow of current) increases, the amount of current decreases. As voltage increases, the amount of current increases.

To understand Ohm's law you should be able to choose any one of the three quantities and explain how it relates to the other two. It is boring to read about but very interesting to experiment with =]

Answer 3

The resistance is directly proportional to the voltage, provided the temperature remains constant.

Answer 4

The relationships between Power, Voltage, Current, and Resistance. One ohm is the resistance value through which one volt will maintain a current of one ampere.

Hard to give much more in < 30 words, for more info tho

I=current, V= voltage, R= resistance :   I=V/R    R=V/I     V=IR

W=Power  W=VI, W= I²R, W= E²/R

I know you asked for it not to be technical, but that's a bit like saying - make me an engine - but don't use any metal please.

If we were allowed a LOT more than 30 words, we could give it a go (analogy with water pipes, constrictions, flow rate etc), but describing it in <30 words in laymans terms with at least a hint of accuracy is a bit of a tall order.

Answer 5

V = IR, where V is the potential difference  I is the amount of current in amperes that is flowing between these two points, and R is the resistance in ohms of the conductor at constant temperature and strain

Answer 6

Voltage  equals current times amount of resistance.  V (volts) = A (amperes) x R (resistance in ohms), or E (electromotive force or volts) = I (current) x R.

Answer 7

in simple words....

as voltage increases the current increases
