What is metric unit of resistance?
It is the ohm.
Who discovered the mathematical law of electrical current?
Are you talking about Ohm's Law. Voltage = (Current) x (Resistance). Georg Ohm
What is the slope of the graph of versus for an ohmic material?
"Ohmic" means it obeys Ohm's law (V=IR, i.e., voltage = current x resistance). Since Ohm's law can be understood to be a definition of resistance, what this really means is that the material has a constant resistance. In such a case, the slope of current as a function of voltage will be a straight line passing through the origin.
What kind of math do you need to be an electrician?
Arithmetic and basis algebra are good skills to have. For example, Ohm's Law says Voltage = Current x Resistance. If you know Resistance and Voltage and want to solve for current you need to know that Current = Voltage / Resistance.
Is 0.746 M ohms greater than 1 K ohm?
Yes.
What is ahigher resistance 10 ohm or 1 kilo ohm in other words does 1kilo ohm have more or less resistance than 10 ohm.?
Because 1 kiloohm is 1000 ohms. 1000 ohms is a higher resistance value than 10 ohms.
What is resistance if less than 1 ohm?
1 Ohm represents nearly no resistance to current flow, at all. The word, Ohm is usually capitalized as it comes from a person's name.
Why watt density too high mega ohm is low?
ohm's measure resistance, the more ohm's the more resistance the less voltage
Why insulation resistance is given in mega ohm?
If it were less than a number of Megohms it would not be insulation.
What is the resistance of agood conductor?
as little as possible like less than one ohm would be really good.
The resistance of earth wire in ohm is?
5 ohms or less.
What is the acceptable value of contact resistance for circuit breaker in service?
A low voltage (less than 1000 VAC) circuit breaker for 15 A typically has a contact resistance of 0.01 Ohm or less.
What equipment is used to test if armature is shorted?
An ohm meter.
What SI unit is used to measure resistance?
The units for resistance is Ohm (Ω).The standard unit of resistance is the ohm (with a lower case 'o'), named after the German physicist Georg Simon Ohm.
Is an 8 ohm sub woofer better than a 4 ohm sub woofer?
no the higher the ohm the more resistance in the speaker the lower the resistance the more power it will use so if they are the same make the 4 ohm should be louder
Set up 2 4 ohm sub to 2 ohm?
If you are trying to pump a 2.4 ohm sub with a 2 ohm rated amplifier you should be fine. The rating on the amplifier is the least resistance it should have on its load. Anything less than 2 ohms would fry your amp.
What does ohm sign symbolize?
The ohm symbol (Ω) represents electrical resistance in a circuit. It is used to denote the opposition to the flow of electrical current. The higher the resistance, the more difficult it is for the current to flow through the circuit.
