Thet resistor opposes the flow of current through it becoz of its internal construction. Its material has opposing property.

How does loading effect affect flow of current?

Ohm's Law says that Voltage = Current x Resistance (Load). Therefore Current = Voltage / Resistance and as resistance decreases current increases and as resistance increases current decreases.


Does resistance depend upon current?

The higher the resistance the lower the current flow. It restricts the flow of electrical current. The resistance will not depend upon the current. The current flow will depend on the resistance.


How can an ammeter be connected in a circuit and not effect the flow of current?

The ammeter does affect the flow of current in a circuit, however, the resistance of the ammeter is so small in comparison to the circuit that the effect is negligible. It is connected in series.


What effect does decreased resistance have on a circuit?

resistance is the opposition to the flow of an electric current, therefore the current will decrease as the resistance increases. Resistance also creates heat. This is how the light globes in a circuit light up.


How does resistance effect the flow of current in a wire?

Resistance in a wire causes a decrease in the flow of current. This is because resistance impedes the movement of charge carriers through the wire, leading to a reduction in the overall current. Ohm's Law (V = I x R) shows the relationship between voltage, current, and resistance in a circuit.


What is the role of resistance in an electric circuit and how does it affect the flow of current?

Resistance in an electric circuit is the opposition to the flow of electric current. It is measured in ohms. Resistance affects the flow of current by reducing it, as higher resistance leads to lower current flow. This relationship is described by Ohm's Law, which states that current is inversely proportional to resistance in a circuit.


How will you describe the graph of resistance against current?

If resistance is high that time the current flow is low. Bcoz current always flow through the low resistance path.


Why must you make current flow through the meter in order to measure it?

You don't. ...unless you want to directly measure the current in a circuit branch. That's the purpose of an ammeter. You can also use a volt meter if you know the resistance of a resistor in that branch to determine current (assuming DC circuit here) - current = voltage / resistance. This may be more useful for circuitry that is on a breadboard, since inserting an ammeter may not be practical.


The opposition to the flow of electrons through a conductor?

In the simplest case, that would be resistance - but there is also another type of opposition (only relevant for AC) called reactance. The combined effect of resistance and reactance is called impedance.


What does a variable resistor do and how does it affect the flow of electric current in a circuit?

A variable resistor is a component that can change its resistance value. By adjusting the resistance, it can control the flow of electric current in a circuit. Increasing the resistance reduces the current flow, while decreasing the resistance increases the current flow. This allows for precise control of the current in a circuit.


What effect does heat have on electric current flow?

Increasing heat can increase the resistance of the material through which the current flows, which can reduce the flow of electric current. However, in some cases, heat can also increase the kinetic energy of charge carriers, leading to increased current flow in certain materials like semiconductors.


What do you mean by heating effect of current?

Current flowing through any conductor encounters resistance in that conductor. This resistance produces heat. (Think of tires on a car after driving on the highway. Smooth trip, but a small amount of friction (resistance) is inevitable.
