Part of the secondary winding of a transmitters power transformer is accidentally shorted. What should be the immediate effect?

🔍 Key Concepts

• Ohm’s Law and how current changes when resistance changes • Behavior of a transformer secondary winding under a short circuit • Difference between an immediate effect and later damage (overheating/burning)

💭 Think About

• If part of the secondary is shorted, what happens to the effective resistance seen by the source? Higher or lower? • When resistance drops suddenly, what happens to the current in that part of the circuit, according to Ohm’s Law? • Which of the choices describes what would happen first, and which describe possible consequences if the fault remains?

✅ Before You Answer

• Check which option best describes the instantaneous electrical response (current vs. resistance) rather than later thermal damage • Verify whether a short circuit tends to make current increase or decrease in the shorted portion of the circuit • Confirm whether protective devices like circuit breakers respond to excessive current as an initial effect or only after something burns

Question 1 of 27070

Part of the secondary winding of a transmitters power transformer is accidentally shorted. What should be the immediate effect?

The current would rise to an excessive value and trip the circuit breaker

The short would burn the transformer

The current in the secondary winding would decrease

None of the above
