How can you verify that the resistance of a conductor is temperature dependent?

Why do we use fuses in the household circuit?

Suppose you have three resistors each of value $30 \mathrm{\Omega }$. How many resistors can you obtain by various combination of these three resistors? Draw diagrams in support of your predictions.

Draw a circuit diagram for a circuit in which two resistors A and B are connected in series with a battery and a voltmeter is connected to measure the potential difference across the resistor A.

In the figure, the potential at A is _____ V, when the potential at B is zero.

If resistance of your body is $100000 \mathrm{\Omega }$, what would be the current flowing through your body when you touch a $12 \mathrm{V}$ battery?

A uniform wire of resistance $100 \mathrm{\Omega }$ is melted and recast into wire of double length that of the original. What would be the resistance of the new wire formed?
