Question

the potential difference across a wire is 75 volts and its electric resistance is 30 ohms find out the electric current through the wire​

Answer 1

Given,

p.d. (V) = 75 volts

resistance (R) = 30 ohms

current (I) = ?

As we know,

V = IR

=> 75 = I × 30

=> I = 75/30

=> I = 2.5 A

mark me brainliest if it's helpful to uhhh....!!!!

Answer 2

Answer:

Explanation:

I=V/R

=75/30=2.5 A
