JEE Main 2024 — Alternating Current Question with Solution

JEE Main 2024 (30 Jan Shift 1)

Question

Primary coil of a transformer is connected to 220 V AC. Primary and secondary turns of the transforms are 100 and 10 respectively. Secondary coil of transformer is connected to two series resistances as shown in figure. The output voltage V0 is :

Correct answer
A7 V

Step-by-step explanation

Ratio of EMF developed will be given by,

εpεs=NpNs=10010⇒εs=22 V

Therefore, current in secondary circuit will be

I=2222×103=1 mA

Hence, potential drop across 7 kΩ will be V0=I×7 kΩ=7 V
