How much current will an electric bulb draw from 220 V source if the resistance of the bulb is 1200 Omega ? lf in place of a bulb, a heater of resistance 100 Omega is connected to the sources calculate the current drawn by it .

Answer»

Solution :`I_(1) V//R_(1)= (220V)/(1200)=0.18 ` Amp.
`I_(2) = V//R_(2)=(220V)/(100)= 2.2 ` Amp.
