Is ohms law applicable to all the current carrying conductors?

Anonymous

∙ 11y ago

Updated: 8/11/2023

Ohm's law is a linear approximation for the voltage versus current across a conductor. This approximation works very well for good conductors (like metals) as well as poor conductors (like wood), but not very well for semi-conductors (like Silicon).

No. Ohm's law is valid for any substance. Even semiconductors, and substances that we would call 'insulators'.

Is Ohm's Law applicable in alternating current?

Yes, Ohms law is applicable in altering current.

Will maximum current flow through 0 ohms of resistance?

In theory, you would get infinite current. But, of course, in practise, this cannot happen, as any large current would cause severe damage to the source supplying that current, not to mention the conductors involved. Protection against such currents would be provided by a fuse or circuit breaker.

Is a miliohm 1000 ohms?

No, a miliohm is 0.001 ohms. A kiloohm is 1000 ohms.

What is the current in a parallel circuit which has two resistors (17.2 ohms and 22.4 ohms) and a power source of 6.0 volts?

By Ohm's Law, current is voltage divided by resistance, so a voltage of 6 volts across a resistance of 24 ohms will develop a current of 0.25 amperes.

What effect are there when resistance is increased in the size of the current?

Current is inversely proportional to resistance. If you double the resistance, you halve the current. Ohm's Law: Volts = Amps * Ohms Solve for Amps: Amps = Volts / Ohms

What is meant by electric resistance of a conductor?

Electric resistance is a measure of how much a material impedes the flow of electrical current. It is denoted by the symbol R and is measured in Ohms. Conductors with higher resistance require more energy to push current through them.

How many amperes of current will flow in a circuit if the voltage difference is 9 V and the resistance in the circuit is 3 Ω?

Ohm's Law: Current = Voltage divided by resistance 9 volts divided by 3 ohms = 3 amperes.

How do conductors obey the Ohm's law?

Very few conductors obey Ohm's Law, and its the rise in temperature of the conductor when current flows though it that prevents it from obeying Ohm's Law. Some alloys, such as constantan, obey Ohm's Law over a limited range because, over that range, changes in temperature don't affect their resistance. It's really time that we stopped teaching Ohm's Law, as it is not universal, and applies to very few conductors and hardly any electronic components!

Resistance to current flow is measured in?

Resistance to current flow is measured in ohms, denoted by the symbol Ω. It quantifies how much a material or component impedes the flow of electric current through it.

What are watts amps and ohms?

Watts measure power, or the rate at which energy is consumed or produced. Amps (amperes) measure electrical current, or the flow of electrons in a circuit. Ohms measure electrical resistance, or the opposition to the flow of current in a circuit.
