an electric iron drawes a current of 34 ampere from 220 volt supply line what current will this electriv iron draw when connected in 110 volt supply line |
|
Answer» (1) Given V1 = 220 Volts & I1 = 34 Amp.Resistance R= V/ I = 220/34=6.47 Ohm(2) When connected to 110 Volts line, V2 = 110 V and I2 = V2/R =110/6.47 =17 Amp.simply, when voltage is REDUCED to half, current is also reduced to half and POWER is deduced to 1/4 th. |
