Electric power P = VI. For 60W, 120V bulb, current is: MCQ with Answer and Explanation

Electric power P = VI. For 60W, 120V bulb, current is:
A. 7200 A
B. 0.5 A
C. 2 A
D. 180 A
Answer: Option B
Solution (By JKExamLibrary)
I = P/V = 60/120 = 0.5 A. Direct power formula application. Memory tip: 'I = P/V for resistive loads; always use consistent units'. Basic electricity numerical frequently tested in competitive exams to verify formula application and unit handling.

Question #3
Beta rays consist of:
A. Electromagnetic waves
B. High-speed electrons
C. Helium nuclei
D. Neutrons

Correct Answer: Option B


Explanation:
Beta (β) rays are streams of high-speed electrons (β⁻) or positrons (β⁺) emitted during radioactive decay. Beta-minus decay: neutron → proton + electron + antineutrino. Alpha rays are helium nuclei (²He⁴); gamma rays are high-energy photons; neutrons are neutral particles. Memory tip: 'Beta = electrons; Alpha = He nucleus; Gamma = photons'. This classification question tests knowledge of radioactivity types, crucial for modern physics in competitive exams. Always distinguish penetration power: alpha < beta < gamma.
