Ответ:
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.
Ответ:
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.
Put V = 220 V and I= 4 A.
R= 55 ohms
Therefore, the value of resistance is 55 ohms.
