A child has drawn the electric circuit to study Ohm's law as shown in figure. His teacher told that the circuit diagram needs correction. Study the circuit diagram and redrqw it after making all corrections.

Draw a schematic diagram of the circuit for studying ohm's law.

Study the circuits shown in the figure . Answer the following questions Can the r.m.s. current circuit be b large than that a

Write ohm's law. Draw a circuit diagram to prove it experimentally in the laboratory?

In an experiment to determine equivalent resistance of two resistors R_1 and R_2 in series, which one of the following circuit diagrams shows the correct way of connecting the voltmetr in the circuit?

Direction. In the follwing questions, a statement of assertion is followed by a statement of reason. While answering a question, you are required to choose the correct are out of the given four responses and mark it as (A). If both assertion and reason are true and reason is the correct explanation of the assertion, (B) if both assertion and reason are true but reason is not correct explanation of the assertion. (C) if asssertion is true, but reason if false, (D) if both assertion and reason are false Assertion : Kirchhoff's first law for electrical circuits acounts for conservation of charge. While the second law conservation of energy. Reason : Because charge ha discrete nature and the current supplied by the battery in the circuit comes at the expense of chemical energy stored in it.

Study the following electric circuit and find potential difference across 4Ohm resistor

Draw a circuit diagram of an electric circuit containing a cell, a key, an ammeter, a resistor of 2 ohms in series with a combination of two resistors (4 ohms each) in parallel and a voltmeter across the parallel combination. Will the potential difference across the 2 ohms resistor be the same as that across the parallel combination of 4 ohms resistors? Give reasons.

Direction. In the follwing questions, a statement of assertion is followed by a statement of reason. While answering a question, you are required to choose the correct are out of the given four responses and mark it as (A). If both assertion and reason are true and reason is the correct explanation of the assertion, (B) if both assertion and reason are true but reason is not correct explanation of the assertion. (C) if asssertion is true, but reason if false, (D) if both assertion and reason are false Assertion : An electric bulb becomes dim, when the electric heater in parallel circuit is switched on. Reason : Dimness decreases after sometime.

Three students X,Y and Z performed an experiment for studying the variation of alternating currents with angular frequency in a series LCR-circuit and obtained the graphs shown in the figure They all used a.c sources of the same r.m.s. value and inductances of the same value. What can we conclude about the resistance values used by them
