Q1PhysicsUnit 12: Current Electricity

In the circuit shown, the heat produced in

5 \Omega

resistor is 10 calorie/sec. The heat produced/sec in

4 \Omega

resistor will be :

Q2PhysicsUnit 12: Current Electricity

Q Type your question- and of fixed emf, the resistor

\boldsymbol{R}_{1}

has fixed resistance and the resistance of resistor

\boldsymbol{R}_{2}

can be varied (but

\boldsymbol{R}_{2}

is always nonzero). Then the electric power delivered to the resistor of resistance

R_{1}

is independent of the value of resistance

\boldsymbol{R}_{2}

Reason f potential difference across a fixed resistance is unchanged, the power delivered to the resistor remains constant.

Frequently asked questions

How long should a Electrical energy and power, electrical resistivity and conductivity mock test take?

For a topic-level test, aim for 20–30 minutes. For a full subject mock, allow 60–90 minutes to mirror JEE timing.

What is a good score on a Electrical energy and power, electrical resistivity and conductivity mock test?

Aim for 70%+ accuracy initially, then push toward 85%+ as your exam date approaches. Review explanations for every wrong answer.

Does Goodmarks score mock tests automatically?

Yes. Each MCQ is scored instantly with the correct answer and explanation shown after submission.

Can I retake the same mock test?

Pro users can generate new question sets by topic. Reattempting the same questions after a gap is excellent for retention.
