Question

36. Write the relation between electric power (W) of a device with potential difference (Volt)
across it and current (1) flowing through it. P
37. What is electrical resistivity in a series circuit comprising of a resistor having a metallic

Answer 1

Answer:

36. P=VI

Explanation:

we have an expression V=W/I

from this we get W=VI

here power is work done so in above expression we will substitute the value

P=VI

Answer 2

Answer:

36 A.p=vi .37.a.constant of.proportinality
