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.
The purpose of a switch is to stop and start a current flow in a circuit. The stopping of a current flow in a circuit effects the load of the circuit by stopping its action. Resuming the current flow in a circuit also resumes the action of the load.
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

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.
'Electricity' is not a quantity; it's the name of a subject area or topic (just like 'chemistry'). So 'current' describes a flow of charge (not 'electricity'), expressed in amperes. 'Voltage' (potential difference) is responsible for 'driving' current, expressed in volts. 'Resistance' is the circuit's opposition to current, expressed in ohms.
Answer: Inductive reactance is the opposition to the change in current in an electrical circuit and is abbreviated Xl. Answer: The opposition to current flow is called resistance (for DC), or impedance (for AC; often just called resistance); the unit for both is the ohm.
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.
