Theis 60 V when it draws a current of 4 A fromwill the heater draws if

1.	Theis 60 V when it draws a current of 4 A fromwill the heater draws if the potentiai difference is increased to 120 V?potential difference bĂŠtween the terminals of an electric heaterthe source. What current
Answer» resistance offered by the heater =voltage/current =60/4=15 ohms so in second case we have to find the current passing through it that isvoltage/resistance=120/15=8 Atherefore the heater draws a current of 8 A.
