What are the problems with switching AC currents in a circuit of pure resistance at unity power factor?

Power factor does not apply to a resistive circuit. Just the current will follow the voltage (in phase)

What would happen to circuit if there was no resistance?
a circuit with no resistance or zero resistance can be considered as open circuit in which the current is zero. without resistance the circuit just becomes open ()
Is the increase in voltage causes a greater electric resistance in a circuit?
No, the resistance in a circuit does not change when voltage changes. Resistance is an inherent property of the circuit.
How do you calculate the joint resistance in a series circuit with three resistances?
The resistance of a series circuit is simply the sum of the individual resistors.
When a dead short occur what happens to circuit resistance?
The circuit resistance is likely to gradually drop and in such case it will cause the circuit to burn down.
What is critical resistance in circuit theory?
With respect to an RLC circuit, the critical resistance is the resistance which would critically dampen the circuit. This means a resistance lower than the critical resistance would create an under-damped situation, and higher than the critical resistance would create an over-damped situation. An underdamped circuit will ocillate, an overdamped circuit will decay exponentially over a long period of time. The critically damped circuit will immediately decay to zero (time dependent on the values of the circuit elements)
How do you calculate the voltage in a circuit with a resistance of 20hms and a currents of 6?
Use Ohm's Law. In this case, multiply the resistance by the current.
What does a ground fault circuit interrupter look like inside picture wise?
A mechanical switching device, capable of making, carrying and breaking currents under normal circuit conditions. Also capable of making and carrying for a specified time and breaking currents under specified abnormal circuit conditions, such as those of a short circuit.
Why use an enclosed circuit breaker?
To protect the wiring from overheating and catching on fire.AnswerThe term, 'switchgear', describes a variety of switching devices including circuit breakers and isolators (disconnects).A circuit breaker is an overcurrent protection device. Overcurrents are overload currents (due to too much load for a given circuit) or short-circuit currents (due to electrical faults).
Types of switching?
packet switching circuit switching message switching
Data transfer will be faster in circuit switching or packet switching?
Data transfer will be faster in packet switching providing the setup time in circuit switching is greater than the time required to send a packet. If not, that is setup time in circuit switching takes less time, then circuit switching is quicker.
The electric force that makes current flow in a circuit is related to the what?
The electric force that makes current flow in a circuit is related to the resistance.
How me can use 4027 ic in switching circuit?
WHAT IS THE PURPOSE OF IC 4027 IN SWITCHING CIRCUIT
What type of switching does a network use?
circuit switching
In a series circuit How does the voltage from a battery compare to the voltages on each load?
The sum of the currents through the branches of a simple parallel circuit is the current that flows through the voltage source.Kirchoff's current law: The signed sum of the currents in a series circuit is zero. The sum of the currents in the branches represents one effective path, which is in series with the voltage source, so the two effective currents must be the same.
What network technologies does not use circuit switching?
Packet Switching - Computer Communications (Digital)Circuit Switching was used for old fashioned telephony. At present, many companies use VOIP (Packet Switching) for voice communications.
What are the two methods of switching?
1. circuit switching 2. packet switching
What type of switching is used with telephone transmissions?
circuit switching.
