Ohm's Law states that the voltage across a load in a circuit is equal to the product of the resistance of the load and the current flowing through it.
E = I * R
E ==> voltage
I ==> current
R ==> resistance
If you compare an electrical circuit to your household Plumbing, resistance is similar to a restriction or partial obstruction in the plumbing, like a partially open faucet, current is similar to the rate at which water flows through the plumbing or from the faucet, and voltage is comparable to the water pressure.

∙ 9y agoThe law can be written as: V = IR (voltage = current times resistance). More than a "law", it's basically just the definition of resistance (it can be rewritten as R = V/I); however, it's extremely useful in the analysis of electrical circuits.

NCV level 3 question papers for electrical?
ohms law
What is the term for the relationship of voltage current and resistance in simple electrical circuit?
Ohms Law
What is the current in a copper wire that has a resistance of 3 ohms and is connected to a 9-volt electrical source?
3 amperes. Ohm's law: Voltage is ohms times amperes.
How do you calculate 1.67 ohms?
ohms law.
What is the value of the current if an electrical circuit has a voltage of 50 V and a resistance of 5 Ohms?
Ohm's law: Current is voltage divided by resistance. 50 volts divided by 5 ohms = 10 amperes.
What does OHMS stand for?
The ohm is a measure of electrical resistance. It was named for the German physicist Georg Ohm.
What unit measures resistance to electrical current?
Unit measure for resistence is called as "OHM". Its law is called as "OHM'S LAW".
How many ohms is a 120 volts?
"Volts" is electrical pressure applied to a circuit; whereas, "ohms" is electrical resistance to that pressure. One cannot determine ohms from voltage without knowing either the current (in "amps") or power (in "watts"). A normal 120V household circuit can handle a maximum of 20 amps, so using ohm's law of resistance = voltage / current, the minimum resistance required in a 120V household circuit would be 6 ohms. Any less than 6 ohms will cause the circuit breaker to trip.
What is the power dissipated by a parallel resistor of 100 ohms with a 40v power source?
You may find it helpful to use Ohm's law and the definition of electrical power.
What is the Unit of resistance measured in?
Resistance is measured in ohms.By Ohm's law, resistance is voltage divided by current, which is (joules per coulomb) divided by (coulombs per second), which is joules-seconds divided by coulombs squared. (It is easier to just say ohms.)
How do you find conductance using ohms law?
To find the conductance using ohms law,you take the inverse of the resistance(/R)
