Question

Express Ohm's law by a mathematical formula.

a) V=IR
b) I=R/V
​c) R=I/V
​d) V=R/I
​

Answer 1

Ohm's law states that the voltage across a resistor (V) is equal to the current through the resistor (I) multiplied by the resistance of the resistor (R).

Step-by-step explanation:

Ohm's law states that the voltage across a resistor (V) is equal to the current through the resistor (I) multiplied by the resistance of the resistor (R). This relationship can be expressed mathematically as V = IR.
