JEE Main 2026 Current Electricity and Magnetism Practice Questions with Solutions
Check here some of the Current Electricity and Magnetism JEE Main 2026 important questions along with their solutions.
Q1. A 3 µF and 6 µF capacitor are connected in parallel to 12 V. Find total charge.
Solution
Total capacitance C = 3 + 6 = 9 μF
Q = CV = 9 × 10-6 ⋅ 12 = 1.08 × 10-4 C
Answer: 1.08 × 10-4 C
Q2. A current of 2 A flows through a resistor of 5 Ω. Calculate the heat produced in 10 s.
Solution
H = I2Rt = 22 ⋅ 5 ⋅ 10 = 200 J
Answer: 200 J
Q3. A wire of length 2 m and cross-sectional area 1 mm2 has a resistance of 4 Ω. What is the resistivity of the material of the wire?
Solution
Resistance formula: R = ρ L/A
Ρ = R A/L = 4. 1X10-6/2 = 2 X 10-6 Ωm
Answer: 2 X 10-6 Ωm
