What is the total opposition to current flow called?
The total opposition to current flow is called resistance. It is measured in ohms and represents the difficulty that a material offers to the flow of electric current.
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.
What is the Basic Three Electrical Quantities?
The basic three electrical quantities are voltage (V), current (I), and resistance (R). Voltage is the electrical force that moves an electric charge. Current is the flow of electric charge. Resistance is the opposition to the flow of electric current.
What Opposition to the passage of an electric current?
Opposition to the passage of an electric current is known as resistance. It is measured in Ohms and is caused by factors such as the material of the conductor, its length, and its cross-sectional area. Increasing the resistance reduces the amount of current that can flow through a circuit.
What is the opposition to flow of current in a circuit called?
The opposition to the flow of current in a circuit is called resistance. Resistance is measured in ohms and is represented by the symbol Ω.
What is the total opposition to current flow called?

What is resistance reading?
A measurement of opposition to electric current flow in a component or circuit.
What is the opposition to the flow?
resistance is the opposition to the flow of electric charge

What controls the flow of electric current?
The flow of electric current is controlled by the voltage applied to a circuit. Voltage creates an electric field that pushes charged particles (electrons) through a conductor, allowing current to flow. The resistance in the circuit also affects the flow of current, as it determines how much opposition the current encounters.
What Opposition to the passage of an electric current?
Opposition to the passage of an electric current is known as resistance. It is measured in Ohms and is caused by factors such as the material of the conductor, its length, and its cross-sectional area. Increasing the resistance reduces the amount of current that can flow through a circuit.
What are the three elements of electricity?
The three basic elements of electricity are voltage, current, and resistance. Voltage is the force or pressure that drives the electrical current. Current is the flow of electric charge. Resistance is the opposition to the flow of electric current.
The flow of electric charges is called?
The flow of electric charges is current.
What is the term for opposition to current flow within a circuit?
The term Impedance (Z) is used to quantify the opposition to current flow in a circuit.
What is the opposition of current flow measured in?
The opposition of current flow is measured in ohms. For DC circuits it is resistance and for AC circuits it is impedance.
Is it true that In Ohms law the variable i represents the rate of flow of charge which is called impedance?
"I" represents the current which is the flow of electric charge. Impedance is the measure of the opposition to the flow of current at a given voltage usually in a.c. circuits.
