Question

5. What is the SI unit of electric potential? volt
6. State the relation between the powers consumed by a device its resistance R and current lis flowing through it.
7. What is much less heat generated in long electric cables than that in filaments of electric bulbs?
3. Define unit of current.
Ic) Only ferric oxide
(d) None​

Answer 1

Answer:

5) Volt.

6) R is inversely proportional to I.

7)Because filaments of bulb is made of high resistance alloy.

whereas wires are made up of metals having less resistance.

3) S.I unit of current is I.
