I oppose alternating current. Direct is the only way for me. That is 1 in opposition.
In a DC circuit . . . resistance. In an AC circuit . . . impedance.
Because the only opposition to current flow is the resistance of the circuit. This is because, at resonance, the vector sum of the inductive and capacitive reactances is zero.
The opposition of current flow is measured in ohms. For DC circuits it is resistance and for AC circuits it is impedance.
A load increases the flow of electrical current in a series circuit. No load, no flow.
Voltage causes current to flow in an electric circuit.
Total resistance.
In a DC circuit . . . resistance. In an AC circuit . . . impedance.
The term Impedance (Z) is used to quantify the opposition to current flow in a circuit.
Resistance
Impedance.
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.
In an AC circuit, the main opposition to current flow comes from the resistance in the circuit components. Additionally, reactance, which is the opposition to the change in current flow caused by inductance and capacitance, can also play a role in limiting current flow. Finally, impedance, which is the total opposition to current flow in an AC circuit, is a combination of resistance, inductance, and capacitance.
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.
Back EMF.
Assuming you are talking about an AC circuit, then the total opposition to the flow of current in an R-C circuit is called its impedance (symbol: Z), measured in ohms. This is the vector sum of the circuit's resistance (R) and its capacitive reactance (XC) -each also measured in ohms.
A measurement of opposition to electric current flow in a component or circuit.
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.
