E
(2) R=
12t
(3) R = V2P
(4) R = V1​

Answer 1

Answer:

(3) R = V2P

Explanation:

The dimensionally correct expression for the

resistance R among the following is

[P = electric power, 1 = electric current, t = time,

V = voltage and E = electric energy]

(1) R= PI

E

(2) R=

12t

(3) R = V2P

(4) R = V1
