1 resistor has 176ohm resistance (in paralel) ---> given
current (I) = 5 A
Potential difference (V) = 220 V
total resistance = V/I
= 220/5 = 44
let the number of resistors be x ,
176/x = 44
x = 176/44 = 4
therefore the number of resistors is 4. :)

A resistor has a resistance of 176 ohm How many of these resistors should be connected in parallel so that their combination draws a current of 5 amperes from a 220 volt supply line?
4 resistors were connected in parallel it yields 5A of current from 220V supply.
Which resistor is connect 1.5 volt led to series 220v ac?
Typically, a 100 ohm resistor is used to connect a 1.5 volt led to a series 220v ac adapter. Many LEDs can be connected into a string using the resistors.
What size wire required to run 5 amp 220v?
45
What is the required input and output voltages for a personal computer to power on?
input 220v ac & output 24v dc
What is the current and wattage in series and parallel for with two 9 ohm heating elements in a 220V north American circuit?
in series the two elements would have a current of 12.222amps and the watts would be 2688.88889watts. in parallel they would have a current of 48.88889amps and the watts would be 10755.55556
How can you convert a 220v 50hz generator to a 220v 60hz?
you can't
Can you use 220v or 120v appliances in the UK?
UK is 220v
Can you plug kettle 220V 50hz into 220V 60hz outlets?
Yes, no problem.
What has to be done to connect 220v 50Hz refrigerator to 220v 60Hz power supply?
nothing
Can you use a 220v-60hz microwave in Australia?
Yes, using a 220v-60hz microwave in Australia is fine. The voltage of alternating current supplied to homes in Australia is 220v. The frequency of the voltage is 50hz.
What happens to a Nintendo ds i XL 110v when plugged to a 220v?
If you buy the 220 Volt Adapter for the XL it will work fine. If you just plug it in the resistors and hardware within the charger will short out and be unuseable after that. I purchased the 220 Volt adapter for the DSI XL for less that $10.00 from Amazon and it worked fine.
What will happen if you connect 220v bulb in parallel to 100k ohm resistances with supply of 440 v?
This bulb is very likely to be burn out since the 440 supply voltage is very higher than it's rated voltage.
