Question

\A German scientist, George Ohm, discovered the relationship between current, voltage, and resistance. This became known as Ohm's law. Question 20 options: I = V/R I = V × R I = V + R I = V – R

Answer 1

I=V/R is the formula for ohm's law .
I is equal to current
V is equal to voltage
R is equal to resistance
the relationship is as follows
I = V/R
V = I *R
R = V/I

Answer 2

I = V/R

Step-by-step explanation:

According to Ohm’s law, current is directly proportional to the applied voltage. So,

I ∝ V

I = V/R …….. (i)

where,

I = Current in the circuit in amperes (A)

V = Applied voltage in volts (V)

1/R = proportionality constant

From equation (i),

R = V/I ……. (ii)

Where R is called resistance and its units are Ohm (Ω).

Hence, I = V/R is the right answer.
