What is the current rating for a circuit protective device?
The current rating for a circuit protective device, such as a circuit breaker or fuse, is determined by its ability to safely interrupt current flow without damage. This rating is typically specified in amperes (A) and indicates the maximum load the device can handle continuously. It's important to select a protective device with an appropriate rating to ensure safety and prevent circuit overloads. For the most accurate and current information, it's best to refer to specific manufacturer specifications or industry standards.
What are the disadvantages of a double wound transformer?
There is no disadvantage with a current transformer -it does exactly what it's supposed to do, that is:reduce the current flowing in the primary circuit to a value that can be handled by its burden (ammeter or protective relay).electrically-isolate its secondary circuit from the primary circuit.
Which electrical protective device is designed to detect a difference in current location in circuit wires?
A) Outlet plug B) Ground-Fault Circuit Interrupter (GFCI) C) Electricity Read Monitor D) Current Path Detector
What is the voltage across the load R and the current through R when the switch is open in the following circuit?
There is insufficient information in the question to properly answer it. You did not provide details of the "following circuit". Please restate the question.
What is the best method to check a unwanted resistance in a circuit?
Do not add any unwanted device in the circuit. Have correct sized wire for the application and the load current.
What is the Simplest protective device for an electric current?
A fuse is the simplest protective device for over current in an electric circuit.
When electric current is flowing in a circuit if the voltage applied to the circuit is increased the?
Correct Answer= "the current will increase"
In a series circuit there is only one path for current flow?
Correct.

What is the difference between an open and a short?
An open (circuit) is where insufficient (often zero) current flow where some is expected. In this case, little or no work is done. A short (circuit) is where high (often infinite or as limited by the power supply) current flows where only some is expected. In this case also, little or no work is done by the device intended, but there is enough current to trip (or blow) the protective device (fuse or circuit breaker).
Is a circuit breaker a protective device?
yes when combined with a suitable protective relay
What is the simplest protective device for an electric circuit?
Most typically, the most common and easiest-obtainable protective device is - a fuse. A fuse is such a device that is designed to break the circuit if certain conditions are met (typically a level of voltage, current, or a combination of the two).

How to measure current?
To measure current, you would typically use a multimeter set to the appropriate current measurement range. First, ensure the circuit is off, then connect the multimeter in series with the part of the circuit you want to measure the current flowing through. Turn on the circuit to get a reading of the current flowing through that part of the circuit. Remember to set the multimeter to the correct range for the expected current to avoid damaging the meter.
Which electrical protective device is designed to detect a difference in a current between circuit wires and interrupt the circuit and stop the flow of electricity?
A resistor is a device designed to detect difference in current and stop the flow of electricity. On most every type of electric engine or circuit has a resistor.
In an electric circuit the ground prevents current from flowing in the circuit true or false?
In an electric circuit, the ground does not prevent current from flowing. Instead, it provides a safe path for electrical current to return to the earth in the event of a fault. It's a protective measure to prevent electrical shock hazards by maintaining the voltage stability in the circuit. The normal operation of the circuit isn't affected by the grounding system.
