Q4 of 9 Page 137

Of the following, which one correctly indicates Ohm’s Law?


The above is the correct figure as V~I; Hence the figure is correct moreover we always change V and find the current then not vice versa hence V is always on the Y-Axis.

Given below are the diagrams showing the connection of ammeter and voltmeter in a circuit. Of these, which are correct?

 3

The resistance of a 10 cm long wire is 12 Ω. If this is folded into two parts of equal length and included in a circuit, how much will be the resistance produced?

 5

A potential difference of 6 V is applied across a conductor having 12 Ω resistance. How much current will pass through it?

How many times will the current increase if length of the resistor is halved and potential difference is doubled?

 6

What mode of connection of three resistors of 3 Ω each will produce minimum resistance? What will produce maximum resistance? Draw the diagram and calculate the effective resistance.
