Question 1 of 10
What is the primary function of an isolation transformer?
Isolation transformers primarily provide galvanic isolation between the power source and the connected equipment for safety and noise reduction.
Question 2 of 10
What is the typical turns ratio of an isolation transformer?
Isolation transformers usually have a 1:1 turns ratio to maintain the voltage level.
Question 3 of 10
Why are isolation transformers used in sensitive equipment?
Isolation transformers help protect sensitive equipment from voltage spikes and electrical noise.
Question 4 of 10
What type of isolation does an isolation transformer provide?
Isolation transformers provide galvanic isolation, meaning there is no direct conductive path between the input and output.
Question 5 of 10
An isolation transformer is primarily designed to block the passage of:
Isolation transformers block DC components while allowing AC components to pass through.
Question 6 of 10
What is a potential hazard when using an isolation transformer?
Capacitive coupling to the appliance body can present a mild shock hazard.
Question 7 of 10
How does an isolation transformer help protect against voltage spikes?
The primary winding's inductance resists sudden current changes from voltage spikes.
Question 8 of 10
In the context of electrical safety, an isolation transformer helps to prevent what?
By isolating the load, an isolation transformer reduces the risk of electric shock.
Question 9 of 10
What is a major advantage of using an isolation transformer in a medical device?
Isolation transformers are crucial in medical devices to prevent harmful leakage currents.
Question 10 of 10
Which of the following is NOT an application of an isolation transformer mentioned in the text?
While isolation transformers have wide uses, they are not typically used in electric motors.
