WebA resistor has a resistance of 176 ohms . How many of these resistors should be connected in parallel so that their combination draws a current of 5 amperes from a 220volt supply … WebAns is 4 nos Explanation I ( current ) = V (voltage ) / R ( resistance ) . hence to carry 5A at 220 V supply Resistance required V / I = 220 / 5 = 44 OHMS. In parallel circuit 1/R = 1/R1 + 1/ R2 + 1 / R3 so on …. Hence 1 / 44 = n / 176 when n = no of parallel resistance so n = 176 / 44 = 4 More answers below
How Many 176 Ohm Resistors in Parallel are Required?
WebOhm's law calculation formula. The current I in amps (A) is equal to the voltage V in volts (V) divided by the resistance R in ohms (Ω): I =. V R. Example. I =. 20V 10Ω. = 2A. The power P in watts (W) is equal to the voltage V in volts (V) times the current I in amps (A): WebSolution Verified by Toppr R= IV= 5220=44Ω If n number of R resistances are connected in parallel then their equivalent resistance becomes R eq= nR where R=176ohms Now … flydubai refund voucher
