Final answer:
The voltage output of transformers can be ranked based on the number of turns on the secondary coil. Transformer b, with 200 turns, will have the highest output voltage, followed by Transformer c with 100 turns, and lastly, Transformer a with 50 turns.
Step-by-step explanation:
The voltage output of the secondaries in transformers can be determined by the ratio of the number of turns on the secondary to the number of turns on the primary multiplied by the primary voltage. This is given by the transformer equation Vp/Vs = Np/Ns, where Vp is the primary voltage, Vs is the secondary voltage, Np is the number of turns on the primary, and Ns is the number of turns on the secondary.
In the given student's question, all transformers have a primary voltage of 240V and 100 turns on the primary. Comparing secondary turns:
- Transformer (a) has 50 turns.
- Transformer (b) has 200 turns.
- Transformer (c) has 100 turns.
To rank the voltage output from greatest to least:
- (b) 240 V, 200 turns will have the highest output voltage since it has the highest ratio of secondary to primary turns.
- (c) 240 V, 100 turns will have the same output voltage as the primary voltage since the turns ratio is 1:1.
- (a) 240 V, 50 turns will have the lowest output voltage as it has the lowest turns ratio.
Therefore, the ranking from greatest to least voltage output is: Transformer b, Transformer c, Transformer a.
