Q1PhysicsUnit 12: Current Electricity
In the circuit shown, the heat produced in 5Ω5 \Omega resistor is 10 calorie/sec. The heat produced/sec in 4Ω4 \Omega resistor will be :
Q2PhysicsUnit 12: Current Electricity
Q Type your question- and of fixed emf, the resistor R1\boldsymbol{R}_{1} has fixed resistance and the resistance of resistor R2\boldsymbol{R}_{2} can be varied (but R2\boldsymbol{R}_{2} is always nonzero). Then the electric power delivered to the resistor of resistance R1R_{1} is independent of the value of resistance R2\boldsymbol{R}_{2} Reason f potential difference across a fixed resistance is unchanged, the power delivered to the resistor remains constant.
