In an AC circuit, resistance causes energy dissipation in the form of heat, leading to a reduction in the overall efficiency of the circuit. It affects the phase relationship between voltage and current by causing them to be out of phase; the current lags behind the voltage. This results in a decrease in the power factor, which can affect the performance of AC devices. Additionally, higher resistance can lead to reduced current flow, impacting the circuit's ability to deliver power effectively.
What else can I help you with?
What is the total opposition to a current flow in an AC circuit with both resistance and reactance?
Resistance
In a purely resistive AC circuit what have the voltage and current got in common?
both have to confront with resistance.
Impedance in an ac circuit is the combined effect of capacitive reactance and inductive reactance and 1.current 2.power 3.resistance 4.voltage?
Impedance in an AC circuit is the combined effect of capacitive reactance and inductive reactance, along with the circuit's resistance. It is represented as a complex quantity that accounts for both the opposition to current flow due to resistance and the phase shift caused by reactance. Therefore, while current, power, and voltage are related to impedance, the most direct association is with resistance, as it is part of the total impedance affecting how the circuit responds to AC signals.
Why ac pass by capacitor as it has infinite resistance?
ac passes by repeatedly charging and discharging the capacitor. when you study ac circuit analysis, you will find out about impedance and reactance, which will allow you to compute how ac behaves in capacitors and inductors.
In a parallel ac circuit is the current additive?
Yes In parallel circuit , current entering into the circuit will be divided intodifferent paths ( resistances) . Amount of current flow depends upon the magnitude of resistance applied in the circuit. Total current after passing through the circuit will be the sum of all current through each resistance.
What is RL circuit in ac voltage?
An RL circuit is a circuit containing resistance (R) and an inductance (L).
What is the total opposition to a current flow in an AC circuit with both resistance and reactance?
Resistance
What if an ac circuit has both resistance and inductance?
A: Believe it or not they all have these components
Can you measure ohms from a live 115v AC outlet?
No, the circuit should not be energized when checking the resistance of a circuit.
In a AC parallel circuit which is constant voltage or resistance?
Voltage will be constant. Resistance is dependent on the components in the circuit. Source: Electronics Technician for the US Govt

Why don't AC input wires to a transformer just short circuit?
The resistance of the winding in the primary of a transformer constitutes a load. As long as there is resistance then there is no short circuit. A short circuit is considered no resistance which develops an instantaneous high current. That is why fuses and breakers are inserted into the circuit to open the high current flow under a short circuit condition.
What does electricity refer to?
It is the complex ratio of the voltage to the AC (alternating current) circuit. It extends the concept of resistance to AC circuits due to magnitude and phase.
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.
