Question

A music system connected to a 220 volts power supply offers a resistance of 100 ohms to
the flow of current through it. Calculate the value of current in milliamperes.
[Ans: 2200 mA​

Answer 1

Answer:

V = 220volt

R = 100 ohm

By ohm's law ,

V = I R

so ,

I = V / R

I = 220 / 100

= 2.2 A

when we convert it into milliamperes,

1 A = 1000 mA

so ,

2.2 A = 2200 mA

@hope it helps ..
