7. How many 176 ohm resistors (parallel) are required to carry current 5 Ampere on 220 volt line |
|
Answer» -Potential difference (V) = 220 V Current (I) = 5 ATo find :-How many 176 ohm resistors in parallel are required to carry 5 ampere on a 220 volts ?Solution :-we KNOW that,HENCE the total resistance of circuit is 44 Ω.Now,We have to find out how many 176 Ω resistors should be connected in parallel to obtained a resultant resistance of 44 Ω.Let the number of 176 Ω resistors required be x.then,Hence,4 resistors of 176 Ω each should be connected in parallel. |
