Question

Do Correct answer only pls
1.On what factors does the resistance of a conductor depend ?
2. Will current flow more easily through a thick wire or a thin wire of the same material ,when connected to the same source ? Why ?
3. Let the resistance of an electrical component remains constant while the potential difference across the two ends of the component decreases to half of its former value. What change will occur in the current through it ?
4. Why are coils of electric toaster sand electricirons made of analloy rather than a pure metal ?
5. Use the data in Table 12.2 to answer the following –
(a) Which among iron and mercury is a better conductor ?
(b) Which material is the best conductor ?
Pls answer all question

Answer 1

Answer:

The resistance of a conductor depends on the cross sectional area of the conductor, the length of the conductor, and its resistivity. 2. The current will flow more easily through the thick wire than the thin wire. ... If thicker the wire, less is resistance and hence more easily the current flows
