Question

A current of 2 A flows through a resistor. The voltage across the resistor is 18 V.

pls I need this

Answer 1

`R=9\ \Omega`

Step-by-step explanation:

Given that,

Current, I = 2 A

Voltage across the resistor, V = 18 V

We need to find the value of resistance of the resistor. Let the resistance be R. We can find it using Ohm's law i.e.

V = IR

Where

R is the resistance of the resistor

`R=(V)/(I)\\\\R=(18)/(2)\\\\R=9\ \Omega`

So, the resistance of the resistor is equal to
`9\ \Omega`.
