Question

A) Write the names of the materials used in the ohm law according to the Figure 1?

b) If the voltage of a circuit is 12 V and the resistance is 40 , What is the generated power?

Answer 1

a. i. conducting wire

ii high-pass and low-pass filters

iii. Cobra-4 Xpert-link

iii. voltage source

b. Power generated is 3.6 W.

Step-by-step explanation:

Ohm's law state that the current passing through a metallic conductor, e.g wire is directly proportional to the potential difference across its ends, provided temperature is constant.

i.e V = IR

i. conducting wire

ii high-pass and low-pass filters

iii. Cobra-4 Xpert-link

iii. voltage source

b. Given that; V = 12 V and R = 40 Ohm's.

P = IV

From Ohm's law, I =
`(V)/(R)`

So that;

P =
`(V^(2) )/(R)`

=
`(12^(2) )/(40)`

=
`(144)/(40)`

= 3.6 W

The power is 3.6 W.
