What forces can oppose current flowin an ac circuit?

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.

Resistance


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.


Total opposition to current flow in an AC circuit with both resistance and reactance is called?

Impedance.


The opposition to current is called?

It is nothing but giving current in opposite direction (positive to negative andnegative to positive)


Is current is the rate of electrical flow in a circuit and that votage is the opposition of current flow?

'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.
