It doesn't! Ohm's Law simply states that for a limited range of conductors, the ratio of voltage to current is constant for variations in voltage. No mention of resistance. And Ohm's Law only applies to a relatively-small number of conductors; most materials and electrical devices such as diodes, etc., simply do no obey Ohm's Law. Those that do are called 'linear' or 'ohmic' materials or devices; those that don't are called 'non-linear' or 'non-ohmic'.
The equation, V = IR (or, more specifically, R = V/I ) comes from the definition of the ohm, and NOT from Ohm's Law.
What else can I help you with?
How much resistance is in the circuit if it uses a current of 10ma?
Just use Ohms Law: V=IR, that is, voltage (in Volt) = current (in Ampere) x resistance (in Ohms).
State ohms law and give the formula?
The Ohm's law is defined as voltage propositional to current. The equation given by V=IR R IS THE PROPOSITIONAL CONSTANT
What do you mesure the answer of Ohm's law in?
Ohm's law can be used to find the current, voltage or resistance in a electrical circuit. The formula is V=IR where 'V' is the Voltage measured in Volts (V), 'I' is the current measured in Amperes (A) And 'R' is the resistance, measured in Ohms (Ω)
If resistance equals 5 ohm and voltage equals 6v then find current?
Ohms Law! E=IR Voltage equals current times resistance. Get out the old calculator...
The voltage drop in each resistance is?
V=IR by ohms law. Voltage across the resistor is the product of current flowing and resistance of the conductor at constant temperature.
Is V equals IR ohms law?
Some say so.
Can you write ohms law v equals IR in matrix form?
Yes you can... and its handy for solving Kirchoff's law mesh equations[V] = [R].[I] (that's [R].[I], remember order is important when multiplying matrices)
If a toy car with a resistance of 2 ohms is connected to a 3v battery how much current flows through the car?
Ohm's Law: V = IR (voltage = current times resistance).Ohm's Law: V = IR (voltage = current times resistance).Ohm's Law: V = IR (voltage = current times resistance).Ohm's Law: V = IR (voltage = current times resistance).
How much resistance is in the circuit if it uses a current of 10ma?
Just use Ohms Law: V=IR, that is, voltage (in Volt) = current (in Ampere) x resistance (in Ohms).
Is voltage and current are proportional?
Yes, due to ohms law. Current, resistance and voltage are all directly proportional. V=IR; I=V/R; & R=V/I
A resistor consumes 1.0 amps when 120 volts is applied What is the value of the resistor?
V=IR (from Ohm's Law) So, R=V/I =120 ohms
How do you calculate a current?
Current can be calculated from its inter related parameters like voltage, resistance using ohms law V=IR.
State ohms law and give the formula?
The Ohm's law is defined as voltage propositional to current. The equation given by V=IR R IS THE PROPOSITIONAL CONSTANT
What would the voltage be in a DC circuit if there were a current flow of 6 A and a resistance of 8 ohms?
Ohms Law! E=IR Voltage equals current times resistance. Get out the old calculator...
How much voltage does it take to 005amps to flow trough 1 ohm?
by the ohms law v hav v=ir i=5amps r=1ohm so v=5*1=5v
Why resistance value increases as current decreses?
according to ohms law V=IR where V=voltage I=current R= resistance so simply we can say that as I decreases R has to increase to maintain V.
If you multiply amp times ohm the answers will be in units of?
Volts. Using the equation V=IR Change in voltage (measured in volts) = Current (in Amps) * Resistance (in ohms) So a volt equals amps times ohms.
