wat is ohms law?

Answer 1

V = I*R

voltage = current * resistance

Answer 2

Ohm's law is named after George Ohm, the physicist. The law describes the relationship between Voltage, Resistance and Current in an a simple electrical circuit. It's written as Voltage (in Volts) = Current (in Amps) x Resistance (in Ohms)
In simple terms, if a voltage (pressure to move electrons) of 1 volt is applied to a circuit with a 1 Ohm of resistance, a flow of 1 amp of current will result. Again, this is for a simple Direct Current (DC) circuit... A/C circuits are a bit more complex.

Answer 3

OHMS LAW states that -

As long as the physical state of the conductor remains the same, the current flowing thru the conductor bears a constant ratio to the potential difference applied to it.

I = c V

c is constant of proportionality
It is the conductance of conductor
It is modified as

V = I R

R is resistance to flow of current.

The first part of stmt is necessary because the resistance changes with cange in temperature ,length,area,volume and other physical quantities.

If R remains constant,the graph of p.d. versus current is linear.

Hope this much helps!!!

Answer 4

Ohm's law defines the relationship between voltage and current in terms of resistance. E=I*R (Voltage equal current multiplied by resistance). Of course, you do know algebra to solve for any unknown right? I=E/R and R=E/I

Answer 5

Voltage = Current * Resistance,

where units are:

Voltage - volts
Currenct - amps
Resistance - ohms

Answer 6

The Ohms law is like this Ohms, R is a streanght line on graph with Volt,v when that are not other Physical that change like leanght, temperture...
(Sorry, my English are not good)

Answer 7

The voltage across a resistor is the product of its resistance and the current through it, E = IR. It's the most basic relationship between voltage and current, and applies to a purely resistive load. The relationship is different for other passive devices like capacitors and inductors, and for active devices like transistors.

Answer 8

ohm's law states that,
I is proportional to v (at constant temperature).
also the constant of proportionality is designated as R(resistance).
and R=ml/(n*(e to the power2)*relaxation time);
relaxation time is not urs but between the collisions.
l-length
n-no.of electronsper unit volume

Answer 9

voltage=current * resistance, in an ideal conductor
