In a parallel circuit, power P = V²/R. Since both resistors have the same voltage, the thermal energy ratio is inversely proportional to resistance. Thus, E100Ω : E 200Ω = 200 : 100 = 2:1. Answer: (b) 2:1.
Using the formula for parallel battery circuits: V = 12/1 + 13/2 /1/1 + 1/2 = 12 + 6.5/1.5 = 11.67V Thus, the answer is (a) 11.6 V to 11.7 V.
The middle vertical line represents balance, symmetry and discipline in classical dance. It helps maintain body alignment, ensuring precision in movements, postures and transitions, creating an aesthetically pleasing and structured performance in forms like Bharatanatyam, Kathak and Odissi. Class 6 Visual ...
Let the emfs be E₁ and E₂. From the potentiometer principle: E₁ + E₂/E₁ – E₂ = 50/10 = 5 Solving, E₁/E₂ = 5/1. Answer: (d) 5:1.
