Question

Voltage = 220 v Current = 4 amps Resistance = 18 55 224 880

Answer 1

Answer: The correct answer is 55 ohm.

Step-by-step explanation:

The mathematical expression fro ohm's law is as follows;

V=IR

Here, V is the voltage, I is the current and R is the resistance.

It is given in the problem that Voltage = 220 v Current = 4 amps.

Calculate the resistance by rearranging the expression.

$R=\frac{V}{I}$

Put V = 220 V and I= 4 A.

$R=\frac{220}{4}$

R= 55 ohms

Therefore, the value of resistance is 55 ohms.

Answer 2

Hi.

I believe the formula for R when you have the voltage and current is:

V/I = R

Plugging in the numbers:

220/4 = 55

The answer is the second option, 55.
